The best information about adjusting carburetors on a chainsaw

Greetings to you dear and most faithful readers of my blog. In this article, I decided to look at how to adjust the carburetor on a chainsaw. After all, it seems to me that you have more than once encountered the problem that your “darling” let you down when you needed it most. Do-it-yourself Partner 350 chainsaw repair: video. And because you and I are economical and don’t want to waste money on something we can do ourselves, let’s learn how to adjust the carburetor on our chainsaws with our own hands, without hiring professional repairmen. And as you'll soon see, it's quite easy to do. You don’t even need to do anything special like that. I specifically looked at the adjustment of carburetors of all recognizable brands of saws, each of which has its own tricks and aspects, and in my opinion this is the best information on the network!

Why does a chainsaw stall when heating up?

It often happens that the chainsaw starts when cold, but stalls when it warms up. This behavior of the tool can be caused by the following reasons:

The carburetor is not adjusted correctly. This problem can be identified by how the device starts up when cold. If it is carried out without closing the air damper, and the engine starts without a preliminary flash, this means that after the engine warms up, fuel floods the spark plug. The solution to this problem is to adjust the carburetor. Details about carburetor adjustment
Malfunction of the coil (ignition module). This problem can be identified by sequentially checking the spark, first on a cold and then on a hot engine. If there is no spark on a hot engine, then you need to replace the ignition coil.
Spark plug faulty. In this situation, as in the case of a faulty ignition module, the spark disappears when the engine heats up. You need to replace the spark plug with a new one, and if this does not solve the problem, you should check the ignition module and the distance between it and the flywheel.

So let's get started!

What is still useful for you?

Firstly, a summary of the operation of the device itself.
Secondly, the tachometer. Features and advantages of the Partner 371 chainsaw and technical characteristics of the Partner 371, independent adjustment of the ignition and carburetor. Why exactly it will be useful to us, we will look at it a little later.
Thirdly, a screwdriver.

Surprisingly, this is all we will need.

First, take a close look at the structure of your saw. What you need to do first is find where the carburetor jets are located, and what is even more important than the jets is the adjusting screws. Partner chainsaw price 350 from 5 chainsaw carburetor adjustment at work - video. Usually there should be two or three screws. Setting up the partner 350 s chainsaw, adjusting the carburetor of the partner 350 chainsaw. One of them regulates idle speed, and the other two regulate low and high speed.

Specifically, you will need to adjust them, or tighten them, or unscrew them in order to enrich or lean the fuel mixture.

If you need to lean the mixture, simply turn the regulator clockwise; if you need to enrich it, then turn it counterclockwise.

To adjust the idle speed, the screw that is responsible for this also needs to be either turned clockwise to increase the speed, or, you guessed it, in the opposite direction to reduce them.

The need for adjustment

Adjusting the Partner -350 chainsaw is required in the rarest cases; more often, difficulties arise, expressed in the incorrect supply of fuel or wear of the engine. But there are signs that the mechanism needs to be adjusted, here are some of them. After starting the engine, it immediately stalls. In some cases, users cannot start it at all, and the reason lies in a lack of fuel or an excess of oxygen. A problem may appear if fuel consumption increases, resulting in an increase in the volume of exhaust gases. This may occur due to the mixture being oversaturated with fuel.

Mechanical causes of failure

Adjusting the Partner -350 chainsaw can also be useful in case of mechanical failures. For example, due to exposure to strong vibrations, the protective cap may be damaged. As a result, the bolts in the carburetor lose their fixation. The piston part of the engine may also wear out. Tuning the carburetor helps in this case for a certain time; to solve the problem, it is necessary to change the worn part. The prerequisite may be a blockage that appears due to the use of low quality fuel. Damage to the filter and scale build-up can lead to similar consequences. In this case, the carburetor will need to be disassembled, thoroughly washed and adjusted.

The procedure for checking and adjusting the correct operation of the engine

The most vulnerable element of a carburetor engine is the spark plug. It also allows us to judge the probable causes of malfunction of individual components of a gasoline engine. The following procedure is recommended.

Remove the spark plug and inspect it. A dry spark plug with a slight brown tint to the electrodes can be considered serviceable.

Carbon deposits on the spark plug

Chainsaw ignition coil

When installing a new electrical module on the engine, the magneto clearance should be adjusted. The optimal distance between the flywheel and the ignition coil is 0.2-0.4 mm for most chainsaws.

Gap between magneto and flywheel

To be sure, it is recommended to carefully study the documentation for the purchased model and follow the manufacturer’s requirements.

With such a small gap, it will not be possible to use the available measuring tool for direct measurement. In practice, for the Husqvarna saw, a template is used in the form of a spacer, cut from a thin and flexible sheet material of the required thickness. It is clamped in the space between the flywheel and the coil when installing it, and then pulled out.

To avoid the need to adjust the ignition, operate the tool carefully, avoiding impacts. In particular, this applies to chainsaws with electronic chips in the ignition system, as they are very sensitive to mechanical damage.

Carrying out the adjustment

If you have a Partner -350 saw, you can adjust the carburetor yourself, without the involvement of specialists. Having assessed your capabilities and experience, proceed to disassembly, recommendations for which were presented above. You can then make adjustments and subsequent adjustments. It is necessary to distinguish between three screws; this is the number of them that the “ Partner ” saw has, however, in some models the screw is installed in a single copy. The manufacturer designated each with its own letter, which will allow you to understand what the element is intended for. Therefore, the screw under the letter L must be engaged when setting the low speed. The upper speed can be adjusted with a screw under the letter H. The idle speed can be adjusted with a screw under the designation T; other models may only have it.

Need for adjustment

In order to understand how to adjust the Partner -350 chainsaw, it is best to familiarize yourself in more detail with the structure of this unit at the first stage. If you understand the operating principle and components, you will be able to independently determine the cause of the breakdown. The carburetor acts as one of the main parts of the engine, which is necessary for the preparation and subsequent supply of fuel, the latter consisting of fuel and oxygen. If the ratio of these ingredients is violated, the motor may begin to work incorrectly and subsequently fail.

Carburetor design

If you decide that adjustment of the Partner -350 saw is necessary, then you first need to study the design of the elements. The system consists of a diffuser that acts as a constriction to increase the oxygen flow rate. The diffuser is located in close proximity to the inlet through which the fuel is supplied. The carburetor also has a tube with a cross flap; it is necessary to regulate the flow of oxygen. The fuel comes from the atomizer, which is represented by a needle. To regulate the fuel at the entrance to the channel, a float chamber is needed; it is also present in the carburetor device.

Principle of operation

If you purchased a Partner -350 chain saw, you may need to adjust the carburetor during operation. In order to perform these actions correctly, you also need to become familiar with the operating principle of this piece of equipment. The fuel is atomized in the diffuser by a stream of air, which allows you to create a mixture that is pumped into the cylinder. The greater the volume of fuel supplied, the higher the engine speed will be. In the described model, as in any other, the carburetor operates according to the same scheme described above.

Replacing the piston group

If it is necessary to replace the cylinder and piston of the Partner 350 chainsaw, it must be disassembled according to the algorithm described above. The piston is secured at the top of the crankshaft connecting rod using a piston pin. A separator with roller bearings is installed between the pin and the connecting rod.

To replace the piston and cylinder, it is necessary to remove the piston from the cylinder and remove it from the crankshaft; to do this, remove the piston pin stopper from one side of the piston using pliers and a small screwdriver.

Then it is squeezed out from the opposite side using a small screwdriver. If the pin comes out tightly, you can slowly knock it out using a hammer and a drift, suitable in size, but smaller than the diameter of the piston pin mounting hole.

To check the correct installation, you need to take the crankshaft with the piston installed on it so that the shaft on which the flywheel is installed is in your left hand, with the arrow facing away from you.

After the new piston is mounted on the crankshaft, a ring is installed on it, after which the piston is inserted into the cylinder, while the parts should be lubricated with engine oil, which will prevent the ring from breaking and make the process easier. Next, the crankcase is installed.

Service center technicians use an algorithm for replacing the piston group, which allows the work to be done without completely disassembling the Partner 350 chainsaw. How such a replacement occurs can be seen in the video.

Ignition adjustment

Those people who have a Partner -350 saw adjust the ignition quite often. When starting for the first time, the idle speed needs to be checked; to perform it, you need to turn the screw responsible for adjusting the idle speed clockwise. As soon as it rests, it should be turned counterclockwise 4.5 turns. If after these manipulations the motor runs without rotating the chain, then everything is in order. Otherwise, you need to contact a service center, since working with such a saw can be dangerous.

How to Replace the Starter Cord

Quite often the starter cord needs to be replaced due to a break. Let's figure out how you can replace it without contacting a service center.

Removing the starter from the Shtil 180 chainsaw is quite simple, without even removing the handle block; to do this, you will need to unscrew the mounting screws and remove the covers of the oil and fuel tanks. Then, slightly lifting and turning the starter, remove it from its seat.

The starter cord is wound on a special drum, which is installed in the body of the part. To replace the cord, there is no need to remove the drum; just remove the broken cord and wind a new one.

Use original Stihl cord of the correct diameter for replacement. If the cord is thicker, the number of turns of cord wound on the drum will decrease, which will lead to a decrease in the starter stroke.

After the cord is wound on the drum, it is necessary to pass it through the starter body and install the handle and secure it with the help of several knots made one after another. Next, the working stroke of the starter is checked, and if everything is in order, the part is installed in place.

A video showing how to replace the starter cord yourself can be viewed below. The master comments in detail on all stages of the replacement, starting from removing the starter and ending with installation.

Chainsaw device Partner 350

The Partner model in the 350th configuration stands out for its excellent selection of components and high build quality. The basis of garden tools is a 2-stroke, 1-cylinder internal combustion engine, running on a mixture of AI-92 gasoline and motor oil. The piston group of the engine is forged and coated with a chrome alloy to extend the working life of the internal combustion engine. The factory engine includes a proprietary CCS filter, which is distinguished by its ability to capture the smallest foreign particles, preventing them from entering the fuel.

The Partner 350 chainsaw differs from its analogues in its simplified starting, which was achieved thanks to a modified starter with a self-cleaning drum, a professional fuel pump and durable electronic ignition. To pre-pump the used fuel into the cylinder, the model is equipped with a primer.

For the safety of the operator while operating a running chainsaw, the Partner company has equipped the garden tool with a high-quality inertia brake, which is instantly activated when the saw set hits a nail or any other foreign object.

The working parts of the Partner saw are a metal bar and a chain. Their tension is carried out using two keys, without the need to remove the protective cover of the plastic case.

One of the main advantages of the Partner 350 chainsaw is the convenient location of the controls necessary for operation. The throttle lever, combination switch and factory starter cable are located at the rear of the tool, making it much easier to operate in tight spaces.

Service

The fuel mixture used consists of AI-95 or AI-92 gasoline and oil for two-stroke engines. Before starting work, it is necessary to run-in the engine at medium speeds and light loads. The ratio of gasoline and oil for Partner 350 chainsaws during break-in is 35 grams per 1 liter. After it, you need to dilute 20 grams of oil with one liter of gasoline. The break-in period for Partner 350 chainsaws should be 1.5-2 tanks.

AL-KO 2-stroke engine oil

An important feature that determines the proper operation of Partner chainsaws is chain tension. You can do it yourself

Poor tension can cause the tire to fly off or be damaged. With excessive tension, the load on the motor increases, which subsequently wears out the saw faster.

The main aspect that determines the safety of working with a Partner chainsaw is the availability of protective clothing. Hands should be worn with gloves made of strong fabric. In general, pants with a special lining that will stop the movement of the saw during emergencies and the same jacket are perfect for the body. Shoes should be just as durable.

It is strongly recommended that owners adhere to the following tips, which will make work much safer and more convenient:

The saw should be kept as close to the body as possible - in this case, the hands will receive less load. This will also help you better maintain balance and control the process.
When changing position, it is necessary to turn off the engine using the chain stop activator. Before performing a maneuver, you need to make sure that it does not rotate.

Also, it is necessary to comply with a number of felling safety requirements:

It is necessary to determine the direction in which the tree will fall. It is necessary to take into account the direction of the wind, the slope of the soil, and the growth of the tree itself.
The space around the tree must be cleared of bushes, undergrowth, and foreign objects. Clearing should be done at a 45 degree angle from the back and sides of the tree.
A safe distance is considered to be two tree lengths. There should be no strangers in this gap.

Chainsaw oil Partner 350 – how to choose?

To extend the life of the engine and other working mechanisms of garden tools, it is necessary to use high-quality motor oil to prepare the fuel mixture. When burned in the cylinder, it should form as little ash as possible, which settles on the walls of the muffler and on the spark plug.

The engine oil used for refueling must quickly dissolve in gasoline and be thoroughly cleaned of harmful impurities, which, over time, settle in the narrow channels of the factory carburetor of the Partner saw.

In addition, Partner 350 chainsaw oil must have high lubricating and anti-corrosion properties, as well as good wear resistance.

It is best to use oils for 2-stroke engines from the Stihl and Husqvarna brands to prepare the fuel mixture. They lubricate the operating components of Partner garden tools well and, when burned, do not emit a large amount of ash.

Structural components

All two-stroke gasoline engines have a similar operating principle, and therefore the ignition system in them has a standard structure and design.

Chainsaw ignition device:

Magneto: a device that converts mechanical energy into electrical energy and provides a pulse of current to the chainsaw's spark plug;
Spark plug: designed to ignite the fuel-air mixture through a discharge that occurs between the electrodes;

Electrical cable;
Engine shutdown button.

Plugs come in spark, arc, glow and catalytic types. Chainsaws use spark plugs for 2-stroke engines. The schematic diagram of the chainsaw ignition is shown in the image.

Basic malfunctions of the ignition system of chainsaws

Having roughly understood how the ignition system of Chinese or domestic chainsaws works, you can already figure out what problems there may be with this mechanism and how to fix them.

Spark plug

Most often, breakdown occurs due to the spark plug. It is worth checking whether the insulator is damaged and whether the electrode is worn out. The entire spark plug is checked for integrity and absence of defects - this includes the integrity of the wires from the coil, the presence of insulating material, etc.

High voltage wire

Next, check the spark plug wires. Often they can run in such a way that there are many bends. In those places the wire can be damaged, while outwardly looking perfect. Next, inspect the spark plug cap and ignition wire. There should be no brown coating on it. If there is one, this means that the spark does not shoot in the right place, but in all parts near the ceramic insulator. The cap may also have damage - cracks, chips. The check must be carried out carefully, because a damaged insulating layer can result in an electric shock.

On/off button

A frequent breakdown of the ignition system is a malfunction of the shutdown switch. To check it, the wires are disconnected from the module and the functionality of the saw is checked. If there is a spark, the problem is in the switch.

Chainsaw Partner 350 – model characteristics

The high efficiency of the Partner chain saw in the garden was achieved thanks to good factory parameters.

Garden tool specifications include:

The power of the factory internal combustion engine is 1.8 liters. s./1.3 kW;
volume of standard forged cylinder – 36 cm3;
engine idling speed – 4000 rpm;
fuel tank capacity – 400 ml;
oil tank volume – 200 ml;
recommended tire length – 40 cm;
saw chain pitch – 3/8 “;
weight – 4.7 kg.

During operation, the Partner chainsaw creates minimal noise and vibration. The sound pressure on the operator when the engine is running at maximum speed does not exceed 108 dB.

Do-it-yourself adjustment of the Partner 350 chainsaw carburetor

Before you start tuning the standard carburetor of the Partner model, you need to thoroughly clean it of dust, dirt and carbon deposits that have accumulated on the walls. In addition to the carburetor, you will need to wash and dry the fuel and air filters. Otherwise, the operator will not be able to accurately set the required engine speed.

In the upper left part of the protective plastic body of the Partner saw there are holes, inside of which the manufacturer provides bolts for adjusting the carburetor. Having found them, you can begin basic configuration of the node. To do this, the left and right screws, which are responsible for the quantity and quality of revolutions, respectively, must be set to the fully tightened position. Immediately after this, they must be loosened by 1/5 of a turn. The third adjustment bolt, marked T, must be left in the position in which it is installed.

The final adjustment of the Partner 350 chainsaw carburetor is performed in the following order:

First you need to start the saw and let its motor run to fully warm up;
After 5 minutes you can start adjusting. First, you need to start turning the left bolt in the direction of the clock until the engine reaches maximum speed. Then the left bolt must be turned 1.4 turns in the opposite direction. After performing these steps, the Partner chainsaw engine should idle confidently;
If, after manipulating the left adjusting screw, the chain on the bar begins to rotate, then it must be stopped by alternately turning the bolt T;
Then you need to move on to adjusting the quality of the fuel mixture. To do this, the right adjusting screw will need to be turned in the direction of the clock hand. As soon as the motor reaches the maximum permissible speed, the screw must be unscrewed 1/4 turn in the opposite direction.

Features of adjustment on different models of trimmers

The ignition system is designed in a similar way on vehicles from different brands, so the process of adjusting it will look the same. The differences, if any, will be minor. They are mainly associated with disassembling equipment. For example, removing the casing from the engine is performed with some differences on different trimmers. So, on Patriot devices, you first need to unscrew the bolts and disconnect the air filter housing using a slotted screwdriver. After this, the plastic casing will be very easy to remove. A detailed diagram and structure of a trimmer of a certain model is usually shown in the operating instructions for the tool.

So, you can adjust the ignition for a gasoline trimmer yourself. This process is simple if you know the correct procedure. But first you need to exclude possible malfunctions of other components and parts, for example, spark plugs or magneto, which may be the reason for the mower’s engine not starting. However, when disassembling equipment from different brands, you need to take into account possible differences in design, which are described in detail in the user manual.

Chainsaw Partner 350 – ignition adjustment

You need to think about adjusting the ignition of your Partner garden tool when its engine stops starting, or when the rated power of the engine has noticeably dropped. Before adjusting the ignition, you will need to thoroughly clean the spark plug, and also wipe the coil itself from dust.

The further procedure is as follows:

First you need to remove the left cover of the protective plastic case;
The flywheel and ignition coil are located under the cover. They must be located at a certain distance from each other. A template or a regular paper business card will help to set the gap between them;
To make the adjustment, you will need to remove 2 screws located next to the flywheel. As they rotate, the element will move away from the coil;
Next, you will need to place the template firmly on the side of the coil and start turning the screws in the opposite direction;
Once the flywheel makes contact with the template, you will need to complete the adjustment.

After setting the ignition, you need to put the housing cover back in place and check the operation of the Partner 350 chainsaw. If the adjustment of the unit was done correctly, the chainsaw engine will start the first time.

The question arises, what to do then?

Here are some common cases:

The chainsaw
does not start;
If it starts, it works intermittently;
Insufficient power to operate properly.

The chainsaw does not start or does not start well. Reason and how to fix it.

my chainsaw start?

.Cause.How to eliminate.

They have fewer moving parts and no contacts that need to be reset periodically, which often fail. Cause of lawn mower motor failure. The coil used on a modern chainsaw will last until the end of your tool’s service life. The chainsaw has become much more reliable and easier to maintain.

Chainsaw Partner 350 – malfunctions and their elimination

Failures of Partner garden tools can occur for various reasons, the most common of which are improper operation and mechanical shock. To eliminate the malfunction, you will need to determine its exact cause in advance. After this, you can begin repairing the instrument yourself.

Chainsaw Partner 350 starts and stalls

There may be several reasons for this malfunction. Most often, the engine of the tool starts and immediately stalls due to a clogged factory breather, as a result of which fuel does not enter the engine cylinder in sufficient quantity for operation. To fix the damage, you will need to remove and clean the breather. If it is damaged, then it will need to be replaced.

Another reason is the missing connection between the spark plug and the electrical wiring cap. This can happen due to mechanical shock or the formation of carbon deposits from engine oil on the spark plug. To repair the Partner 350 chainsaw, the spark plug will need to be removed and cleaned. In some cases, completely replacing the spark plug may help.

The third reason for the malfunction is that the standard muffler of the chain saw is severely clogged. Over time, carbon deposits form on its walls, which prevents exhaust from leaving the engine. As a result, gases accumulate inside the engine and interfere with its proper operation. To fix the damage, you need to remove the muffler and clean it with compressed air. You will also need to disassemble the engine and bleed its cylinder.

Chainsaw Partner 350 will not start - how to fix the problem?

When this breakdown is detected, the first thing that needs to be inspected is the condition of the air filter. If a large amount of dust has accumulated on it, the filter will need to be washed using clean gasoline.

Another common cause of malfunction is problems with the ignition system. To repair the chain saw, you need to remove its left protective cover and set the correct clearance between the flywheel and the ignition coil.

In some cases, replacing the fuel mixture will help solve the problem. To do this, you will need to drain the used fuel and fill the tank with a new mixture of pure gasoline and motor oil.

What to do if the chain on the Partner 350 chainsaw is not lubricated?

If the chain for the Partner 350 chainsaw is no longer lubricated with oil, this can lead to overheating of the bar and rupture of the saw set. Ignoring this problem also risks increasing the load on the engine, which can lead to engine failure.

The first thing you need to inspect if there is no lubrication on the chain is the oil pump. Over time, the teeth on its drive wear out, which can also occur due to clogging of the pump. It is usually impossible to restore the element, so it is best to replace it.

Often, lubricant does not reach the chain of the Partner 350 chainsaw due to clogged oil pipes. In this case, the hoses will need to be replaced by treating the joints with the fittings with sealant.

Fills a candle on a Partner 350 chainsaw

This common problem is encountered by chainsaw owners who add too much motor oil to the fuel mixture. It does not have time to burn in the cylinder, so part of the lubricant settles on the spark plug and other important elements of the garden tool.

To fix the breakdown, you need to remove the factory spark plug, clean it of carbon deposits and dry it. After this, you need to blow out the cylinder of the factory chainsaw engine by sharply pulling the starter cable several times.

Next, you need to inspect the condition of the carburetor and fuel hoses. Often oil gets on the spark plug due to loss of tightness of the system. This occurs as a result of a break in one of the tubes or a breakdown of the oil pump. To repair a Partner 350 chainsaw, you will need to replace all faulty fuel system parts. After this, you need to install the spark plug in place, start the engine of the tool and check its operation at idle, low and high speeds.

Safety precautions

Partner gasoline-powered chain saws should be handled very carefully, since the fuel mixture is highly flammable, which can cause a fire and, therefore, pose a danger to the operator and surrounding people. Operating the chainsaw in close proximity to flammable gases and liquids is also prohibited.

Due to harmful and toxic fumes, Partner is not recommended for use in enclosed spaces or poorly ventilated areas.

When working with the Partner 340 chainsaw, you should pay close attention to your own protection and safety. When purchasing a chainsaw, you must also purchase protective gloves, glasses, headphones or a hard hat. You can operate the chain saw in fitted clothing that does not restrict movement, as well as in closed shoes with hard soles.

When using the Partner P340S saw with small shrubs or young trees, be careful: young and thin branches can block the chain, which can lead to injury to the operator. Cutting down tense branches can cause a rebound.
