Adjusting the carburetor of the Chinese trimmer for Patriot grass. The principle of operation of the carburetor of the lawn mower

Patriot 555 grass carburetor adjustment

Regulated the carburetor on his patriot 555, everything works exactly, suitable video, thanks.

The carburetor is regulated simply the gas on the full and twist the fuel bolt, when it reaches the peak of power, it is not felt much back so that it would not be too poor the mixture here and all the things

Poor mixture is when little air, rich. when a lot.

@K.O.S.T Offline was wrong. Thanks for the clarification.

Poor mixture is if 1 liter. fuel accounts for more than 17 kg of air. The dosage of fuel is calculated by the amount of air in the virgin lands, so all the ICE work. So there is a lot of air and little fuel. This is a poor mixture.

Good day, a useful video, I bought a Patriot 553, the same story with candles, for a long time could not believe that the factory settings on the carburetor were shot down. Finally decided to set up and the trimmer for the grass earned as it should, the gasoline consumption immediately decreased, I have not yet checked the candle, I think it will be normal. The author is more grateful.

He turned against the sentry for a quarter, tired of waiting for the engine stalled, rejoiced at the trimmer, the hand is really numb in gas.

And thank you for the comment! Happy to help

Such a problem, a trimmer for the grass Patriot 555, a very large fuel consumption of 5 liters per 15 acres

@Fritz Morgan I do not impose anything, adjust as you want

@Pavel Volya of Successful Adjustment. I did not ask me to impose my opinion.

@Fritz Morgan is just so the trimer carburetor is tuned in that is, we find the highest revolutions by twisting or boiling a quality screw and then unscrew the screw for half a turn. This is done so as not to lift the piston so that at high speeds there is no poor mixture and a quality screw from the factory There is a two and a half turn unscrewed for two and a half turning during a trimmer for the grass approximately burning a liter of three gasoline in a gentle mode

@Fritz Morgan Twist the quality of the quality to the stop and turn off for one and a half two turns

Who knows how to set up a needle on a mower?!

You can’t keep it without a casing for a long time, but you can hear that it is overheated

Thanks for the video. but. finally the carburetor must be adjusted during operation. Without load, it can work fine. and die in the load. It is necessary to work and everything will become clear. With uv.

I have the same garbage but.mowing normally and holds the turnover.But the candle acidifies quickly.High speeds for Max are gaining and holding norms.I think I’m always a cat on medium TC How it makes no sense to mow on a maximum wiper.Just fuse gasoline.Maybe because of this.Let it get off that the whole sludge will fly away or.I don’t know what the candle is finging, while the electrode itself is not in oil but a dry black fog

I go to the middle or under load all the time, eats on max Benz. Champion or as it is called correctly, this brand of a candle is 2 years already norms

I have Patriot 3155 and there is no adjustment screw for fuel how to configure ? Only adjustment of the needle

I have 555 on dense grass too hard for him. But large and thick stems mows well, more than a year passed after this setup. I didn’t touch the needle. It’s strange why you don’t have this screw.

K.O.S.Tsfline set up with a needle. You can mow, but the power is not enough on the big grass

I would not touch the needle, it is very difficult to configure, I don’t even know how to set up without a screw, maybe washing will help.

The ignition is adjusted, according to your advice. The candle installed A14ot of the Soviet pile through two sealing rings, since the thread on the BM6A is slightly shorter, it starts from a half. About the adjustment of the carb, I do not agree a little, the delay should not be.

I agree, fulfills its function and this is the main thing. over, this is just China. And they have quality as a roulette, and it is unlikely that these things are in developed countries to consider the repair. This is our inflected this is super cool.

I know why detained, but so far a braid for grass works normally and has not changed candles (with a fishing line there is less delay).

They showed about the carburetor, and the ignition coil is how and why it was not shown. It’s hard to start a trimer, a constant recoil. maybe the starter is a problem, maybe in the ignition, I don’t know.

The coils are regulated when replacing it or as I had on a chainsaw, plowed a corny itself from vibration (just it hit the return)

Hi tell me, my wedge was injected with the engine, we will not tell where you can buy an engine or spare parts thanks

you don’t hear a failure? spin a little screw of enrichment

@Alexey Shchob Tronuchi Trokhno Trokhi Trokhi Trokhi more on the accelerator pedal

@Николай насколько я помню, в СССР не было плохого бензина, и марганец и тетраэтилсвинец на заправках для поднятия октана не добавляли. Which was brought from the oil depot and refuel. The only difference is that then was the 72nd, 76th, and 93rd. Now there is no below the 92nd, but they are driven out of the cheese, which has octane 56-65 (at best).

@Alexey Red Nagar color speaks of poor quality of gasoline, which, with the help of all kinds of manganese and lead additives, is driven under the desired octane number. With a normal ratio, the color of the candle should be sandy- light brown

@K.O.S.T Offline, just in the 4th minute, you had the right one, the braid for the grass briskly gained momentum and without failures.Here are a little more, less than a quarter, and just right! The quality of the mixture (according to old, grandfather methods) is checked visually on all engines as follows: the soot on the candle should be “red brick” or slightly lighter. White-bearing mixture, black-rest. something like this.

Xs, when the screw is too tight, there is no power, it does not mow, at least crack. See how thick grass mows. I used to have a candle in 2 hours, but now the norm. Here you need to catch the line, twist a lot, the poor mixture will be, less butter, more wear of the piston group, you will promote a lot, the candle rabss. For a week he killed over the adjustment and 2 candles, I wanted to give it to repairs. I visited this.

Where to start diagnostics motorcycles

If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main nodes and assemblies. The test algorithm is as follows:

• Fuel tank (fuel quality);
• Candle and candle channel;
• Air filter;
• Fuel filter;
• Breather;
• Graduation channel.

These nodes are most often source of basic problems, which can be eliminated after a thorough inspection.

We diagnose a candle and candle canal

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be the reason. Here, a regular candle key is suitable for repair (every motorist has probably has a spare candle.

• We twist the candle and wipe;
• We thoroughly dry it (you should not bake it);
• Excess fuel in the chamber we drain through the candle hole and dry it;
• We clean the old candle from the carbon on a sugar or a ladies’ file;
• We set a gap with a distance of 1 mm (you can check with any coin);
• We return everything to place and try to start a trimmer for the grass.

Dry the channel at least 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.

If the working candle is working, the nest, where it is located completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly moisturized. No matter what wonderful spark gives out a candle, there is simply nothing to light up in a dry chamber.

Diagnosis of the filters of the lawn mower

Another reason why the gasoline braid for grass stalls is an air filter. To exclude it, try to remove the filter and start a trimmer for grass without it. If it turns out, then you will have to change the air filter to a new one, or at least blow and carefully clean the old.

You can’t start a gasoline trimmer for grass due to contamination of the fuel filter. This is the next stage of our algorithm. Here we check the state of the filter element and, if necessary, change it with the new. When replacing, try not to leave a suction pipe without a filter, this is prohibited by any operating instructions. Rush can turn into the repair of the piston group of the engine.

Sapun and graduation channel

Normal work of cos with internal combustion engines can be disturbed due to dirt from the exhaust channel or clogging of the muffler grid. There is such a problem on the models of the older generation. You can solve the issue with traditional cleaning and removal.

Operating and repair instructions

Correctly choose a gas trimmer for grass. This is a simple task for those who use the device for the first or after winter downtime. Before starting the unit and using the starter, you must fill in the brush with oil. This substance should contain certain additives that easily dissolve in fuel when exposed to high temperatures. Such substances will provide proper protection of the engine elements, protecting against friction even with a large load.

It is not difficult to work a trimmer with a warm engine. To do this, set the switch to the working position, and then tighten the cord before starting. If you follow the instructions, there should not be problems with the launch.

The most common launch errors:

Depending on the work performed, a trimmer for the grass is installed on the trimmer for the grass. Starting a braid for grass means using an engine at a minimum speed without load. For a breakthrough, you must start a brush and use it in standby mode. This step is best performed by inserting the wire, gradually increasing the load level and increasing the engine rotation frequency. After the refusal, the first operation of the device should take about 15 minutes.

Trammers for grass for Patriotes, like any other similar method, should be used with caution, avoiding sudden movements, as well as clashes with extremely hard objects. Let the brushes cool after each use. Also, the user should not forget to put on the belt before using the technique: this element will help optimize the return, as well as distribute the tension throughout the body. The belt should not only be worn, but also fitted under you.

The fact that it is correctly fixed is evidenced by the lack of rapid fatigue of the hands, as well as unpleasant sensations in the muscles.

It should be remembered that the use of a gas trimmer for grass is extremely undesirable in raw and rainy weather. If the device is wet, it should be sent to a dry room, and then dry it. Continuous work of the Patriot bureau can take from 40 minutes to an hour. When working with this device, follow the following precautions:

How to configure a trimmer for Patriot grass

Lawn mowers have long entered our lives as a very useful tool and an excellent alternative to an ordinary spit. The lawn mower and the lawn mower is the same tool. And trimmers for grass are gasoline, and there are electric. In this case, we will talk about gasoline. This unit is quite easy to operate, but has its own characteristics. The lawn mowers are equipped with an internal combustion engine. Carburetor Motokosa is a very important component of the tool. The main task of the carburetor is to ensure the intake of the fuel engine enriched with air into the cylinder. Here the most important thing to observe the balance of fuel and air. The article will talk about the signs indicating the need for adjustment on how to configure the carborer on the trimmer.

It is allowed to adjust the carburetor trimmer for the grass on its own, having previously studied the device of the unit. As a rule, a detailed description of the components of the tool components is in the instruction manual. An experienced master is even able to determine that there are shortcomings in the work of motorcycles. The sound of the motor with proper tuning should be perfectly even. If screaming sounds are clearly audible, then the mixture is oversaturated.

The main problems and malfunctions of the carburetor.

The grid has only two problems with this element:

To determine the cause of the malfunction, unscrew the fuel filter lid to remove the mesh filter. If dirt just accumulated on it, the washing of gasoline or purging will help.

Be sure to install a new filter if there are any visible damage. There may also be damage to the fuel line (check this item during the repair).

The starter of the carburetor in most cases does not work due to blockages. For washing use acetone or the same gasoline.

Filling the parts of the carburetor clogged air is an acceptable and convenient repair practice.

trimmer for grass adjustment grass

The initial stage of restoring the proper operation of the fuel system is the cleaning of the air filter.

Experts recommend rinse it in a solution of water with a detergent every 10-15 hours. Direct adjustment of the carburetor of the trimmer for the grass is carried out by three adjusting screws:

Regulation of fuel supply at minimum speed

Before starting the adjustment of the throttle carburetor, the engine must be warmed up to operating temperature.

To do this, start the engine and let it work at idle for 10-15 minutes. At the first stage, working with a trimmer, slowly tighten the “l” screw before intermittent work or until its death. Then unscrew the screw ¼, turning and check the maximum speed. If the bureau quickly and easily reaches high speeds, it will be the most economical regime. In most models presented on the market, the fuel screw “L” rotates clockwise, but there are trimming tabs, where the decrease and increase in the flow of the mixture occurs in the reverse order.

Monitoring the idle of a trimmer for grass

The location of the screws for adjusting the carburetor

The screw “T” (“AT”) serves as a limiter of the reciprocating movement of the fuel valve, and when it is twisted, the engine speed increases, and its shutdown leads to a decrease in the frequency of rotation of the crankshaft. Professionals advise adjusting the loop of a bush cutter so that the internal combustion engine operates a little faster at minimum speed, but the head with a fishing line or knife remained motionless. If, after manipulations, it is difficult to start the trimmer for the grass “cold”, just turn the “T” screw for a quarter of turn and try to start the engine again.

Skin adjustment at maximum turnover of Kustorez

After the resumption of the supply of fuel at the minimum speed and the establishment of the idle passage, it is necessary to check the stability of the mechanism at increased speed.

The engine is adjustable at high speeds to protect against overheating and reducing the fatigue of the hands when pressing the accelerator key. If the internal combustion engine is unstable at maximum speed, the screw “N” must be screwed slowly to ensure smooth and clear operation.

When working with a bush, it may be necessary to adjust the fuel supply screw (“l”) for optimal speed.

If screaming sounds are clearly audible, then the mixture is oversaturated.

Causes of carburetor breakdowns

When operating, motorcycles (for example, “Patriot” or “Union”) can be damaged, and the user will need to repair it on its own or with the involvement of specialists. This can happen for a number of reasons. One of the most common is non.compliance with the rules for using the device. If, with prolonged operation of the trimmer for the grass, the carburetor was not used and adjusted, the device breaks.

Another cause of the breakdown is an incorrectly prepared fuel mixture. Often the owners of the equipment buy oil and prepare fuel according to the recommendations written on the package of combustible materials, which is incorrect. When preparing fuel, you need to consider the instructions for the operation of the Motokos itself. In addition, the mixture “by eye” should not be made, since incorrect proportions also lead to breakdown of technology.

Most of the breakdowns of carburetors are equally characteristic of motorcycles of different brands, whether Echo, “cedar”, Homelite or the device of another manufacturer.

Signs of unbalancing

Carburetor debugging is necessarily carried out in the manufacture of the device. As a rule, the owners will learn about the need to adjust the fuel supply with their own hands only after quite serious breakdowns, in the process of correcting which, the module was removed and, for example, cleaned.

Signs of failure in the settings are the following:

• starts up, but immediately stalls the engine. since the engine can only work when a certain amount of gasoline is supplied, with too “poor” fuel, that is, overlapping the supply channel, the motor will stop;
• too much fuel consumption, many exhaust gases. the result of incomplete combustion of the mixture. In this case, the fuel, on the contrary, is too much and the mixture is excessively dense.

STIHL, Makita, Husqvarna and others tuned with adjusting screws. Sometimes the reason for disrupting the work is a violation of fixation-due to vibration or damage to the protective cap. Such a breakdown can be found only by trying to turn the screw a little: if the fixation is not stiff, it is worth checking the setting.

Do.it.yourself carburetor adjustment

The setting of the module does not apply to the repair and the change of spare parts is not required. In this case, the armored complex of the carburetor of the lawn mower will not be needed.

• L. is regulated first, as it is responsible for supplying fuel at low speeds;
• H. he is responsible for supplying gasoline at high speeds, as well as for fuel consumption and temperature;
• T. with it, the idle speed is debugged.

There are options, as a rule, this is a carburetor of a Chinese lawn mower, when only one screw remains for debugging on the case. to configure idle. This does not mean that the module is configured automatically. this means that even such a type of repair as debugging will be difficult to carry out. In the photo. adjusting the carburetor of the Chinese lawn mower.

• The module tuning is carried out only with a heated engine: for this, the device is pre.included for 10 minutes. If the mowing head rotates at idle, then they begin to debugged immediately: turn the screw T counts the clock until the rotation stops.
• Adjustment starts with a screw l. The screw turns to the right and to the left until it finds such a position in which the idle speed does not become maximum.
• Then the screw is turned on ¼ turn against the watch. This will be his working position.
• The idle stroke must be configured by turns against the sentry to increase the number of revolutions and the clock. to reduce. Its debugging consists in achieving such a regime in which a sufficient number of revolutions are performed before the rotation of the mowing head. In this case, the engine should operate steadily at different positions.
• The position of the screw L is determined by the latter. at maximum speed the trimmer for grass should not work for more than 10 seconds. The throttle opens, the screw is closed clockwork, very slowly, until a decrease in the number of revolutions is established by ear.
• Then also slowly the screw rotates against the sentry until the engine starts to work with failures. After which the screw is on the time, until the engine again works normally.

If there is a tanometer, and if the product is indicated in the product passport, coooreecration can be carried out more accurate, focusing not by ear, but on the testimony of the device.

Elimination of failures in work

As a conclusion, we describe typical malfunctions associated with improper adjustment of the carburetor and ways to eliminate them:

• The engine does not start or start and stalls after a few seconds. Obviously, the reason is the improper adjustment of the quality of the mixture at low speeds, it is too poor. With a good carburetor, you need to enrich the mixture slightly, unscrewing the screw l at 1/2 turn, and then complete the tune with a screw T.
• The load under load is noticeably losing in power. In this case, the carburetor gives at high speeds too rich the mixture. The screw n needs to be tightened at 1/8 turn, if the load is still not supported by the engine, but progress is noticeable. tighten a little more.
• The engine “sings” on maximum acceleration without load. The mixture at high speeds is too poor, the turns are overstated.
• The engine stalls if you give gas after working at idle. Too poor or rich mixture, or rather, it can be said by the state of the candle.

Common malfunctions of carburetors

Damage of the carburetor of the trimmer for grass occurs due to the use of poor quality gasoline, damaged air filter and the accumulation of dirt in the chamber of this block. Most often, it is quite possible to repair a carburetor with your own hands. Below listed typical malfunctions of the carburetor motorcosa.

Problems of the fuel pump

A common malfunction that “pursues” the fuel pump is a deformation of the pump membrane. For this reason, it does not fit properly, and the pumping canals are not compacted.

The reasons for the deformation of the membrane can be as follows:

As a result, damage to the membrane reduces the productivity of the pump, and, as a result:

• the flammable mixture is impoverished;
• The engine is difficult to launch;
• interruptions in the work of the motor appear;
• The piston is damaged.

Also, the above consequences for the engine can cause clogging of the pump cavity from the pulse side. In this case, dirt enters the membrane through the pulse channel.

To eliminate clogging, you will have to disassemble the carburetor and clean the membrane.

Clogging of the mesh filter

A mesh filter can be contaminated when contaminated fuel is received through a fuel hose or a suction head that has defects. In the photo below you can see how a clean filter and contaminated (parts are separated by a feature).

To eliminate the malfunction, thorough cleaning and flushing of the mesh filter will be required. It is also recommended to blow with compressed air all holes in the body of the carburetor trimmer for grass.

The adjusting lever is faulty

This breakdown appears when the contact surface of the lever wears out.

Washing the contact surface occurs due to the presence of abrasive particles in gasoline or due to strong vibration of the motor during operation. This defect in the adjusting lever causes problems with the inlet, as well as incorrect operation of the motor at idle.

Wear of the intake needle

The inlet needle fails, as a rule, due to the presence of abrasive particles in the fuel fluid.

• The insurance of the saddle of the intake needle is violated;
• the leakage of the combustible mixture appears;
• malfunctions in the operation of the engine associated with re.enrichment of the fuel mixture appear.

Also, the intake needle can simply jam.

Singing an intake needle can cause the presence of dirt in a combustible, or a long simple apparatus without work.

Clogging of the adjusting cavity

If dirt accumulates in the adjusting cavity, then the inlet needle cannot lock the hole tightly and a lot of fuel pours into the chamber.

This causes fuel rewriting, and the engine begins to work incorrectly. It is necessary to disassemble the carburetor and clean the cavity of the adjusting membrane.

Deformation of the adjusting membrane

The membrane may be deformed with prolonged operation of the unit and when using aggressive fuel.

The impossibility of normal adjustment due to the defect leads to:

The problem with the intake adjustment lever

This problem may occur if the adjusting lever is incorrectly, or bend it before installation. As a result, the contact surface takes the wrong position, which violates the additional fuel supply.

Damage to the damper

Throttle and air shutters basically wear out due to the presence of abrasive particles in the air. Defective shutters look as if they were subjected to sandblasting.

As a result of wear of the damper, the engine performance decreases, malfunctions appear in its operation, piston rings, piston and cylinder coating wear out.

Wear of the throttle and air damn

The shaft of air and throttle can wear out for the following reasons:

• insufficient and incorrect air filter maintenance;
• The air filter is damaged;
• The air filter is unsuitable for this device.

Due to the ingress of poorly purified air, the shaft wears out and may break. The broken parts of the shaft can fall into the combustion chamber or the engine of the engine and cause serious damage to the entire piston system.

To eliminate problems with air purification, it is necessary to replace a defective filter or rinse the existing (working). The filter must be washed in soapy water and dried.

Elimination of failures in work

As a conclusion, we describe typical malfunctions associated with improper adjustment of the carburetor and ways to eliminate them:

• The engine does not start or start and stalls after a few seconds. Obviously, the reason is the improper adjustment of the quality of the mixture at low speeds, it is too poor. With a good carburetor, you need to enrich the mixture slightly, unscrewing the screw l at 1/2 turn, and then complete the tune with a screw T.
• The load under load is noticeably losing in power. In this case, the carburetor gives at high speeds too rich the mixture. The screw n needs to be tightened to 1/8 turn, if the load is still not supported by the engine, but progress is noticeable. tighten a little more.
• The engine “sings” on maximum acceleration without load. The mixture at high speeds is too poor, the turns are overstated.
• The engine stalls if you give gas after working at idle. Too poor or rich mixture, or rather, it can be said by the state of the candle.

• Due to severe vibration, the protective cap is damaged, as a result, all three bolts lose their established fixation.
• Due to wear of the engine piston. In this case, the adjustment of the carburetor of the chainsaw will help only for a while, it is better to replace the worn part.
• Due to clogging caused by poor-quality fuel, scale or damage to the filter. The carburetor requires complete disassembly, washing and adjustment.

If the chainsaw suddenly stops working, it must be disassembled to find out the reasons.

Step.by.step instructions for disassembly

The device of the carburetor of models of different brands is almost identical, so as an example we consider the Partner chainsaw. Each element is neatly extracted and folded, so that later it is easier to collect it.

Chain carburators from different manufacturers, if they differ, this is not fundamentally

Remove the top cover by unscrewing three bolts. Followed by foam rubber, an integral part of the air filter.

The arrows indicate the bolts that need to be unscrewed to remove the lid

Then remove the fuel hose and then the drive stem.

The upper hand indicates the fuel hose, lower. on the drive.

The arrow shows the end of the cable that needs to be removed.

Tighten the gas hose to the left of the fitting.

Carefully remove the gas hose indicated by the arrow carefully

The carburetor is constantly disconnected, it is ready to adjust

Its mechanism is quite complex, therefore, if you need further disassembly of the carburetor, the elements should be removed very carefully. They are small so that they can be lost

The carburetor consists of many small details, which during disassembly should be laid out in order

Features of regulation and regulation

To find out how to adjust the carburetor

on a chainsaw, you need to learn to distinguish between three screws (for some models there is only one).

The screws l and h are similar only in appearance, in fact they are different

Each screw has its own letter designation:

• “L” is used to install low speed;
• “H” is required to adjust maximum speed;
• “T” is required to adjust the icy speed (only one screw is present on models with one screw).

The factory adjustment is optimal, and use the screws to adjust the engine operation in special situations (the work is related to various climatic conditions).

The diagram shows the conclusions of the adjusting screws of the carburetor with a closed lid

A special tool is used to install a chainsaw

Adjustment is carried out only by screws l and n. To increase the speed of rotation, they rotate clockwise. Lower. counterclock-wise. The sequence of use of screws: l. H. T.

If you doubt the adjustment, it is better to contact a specialist, since improper adjustment can damage the engine.

On the chainsaws Patriot 4518 and 5220 are similar carburetors. The only difference in performance. T.e. They allow you to work with a larger engine saw.

As for adjusting the carburetor on them, then everything is simple, it passes similarly to the model 3816. You can safely use the instructions described in the article.

The presence of a primer and a light start system Easy Start on models 4518 and 5220 facilitate the launch of a cold engine. Before adjusting the carburetor, you need to verify their serviceability.

In general, Patriot chainsaws due to their average cost and quality are equipped to the best of reliable carburetors, which you need to set up only in extreme measures. If you are not confident in your own abilities, then we strongly recommend entrusting this procedure to the specialists of the service center, t.to. Still, there is a risk of failure, as a result of incorrect tuning the maximum speed of the chainsaw.

Elimination of failures in work

Adjustment of the Patriot 3816 chainsaw carburetor with your own hands

Proper adjustment of the carburetor provides economical fuel consumption and maximum traction characteristics of the Patriot chainsaw. If you regulate incorrectly, then this will necessarily affect her work.

Before starting the adjustment, it is necessary to conduct a complete inspection of the chainsaw, if any, eliminate defects (air leaks, air ducts, etc.).

Usually on the carburetor case (duplicated on the chainsaw housing) there are designations:

• L. the screw is designed to adjust low engine speeds.
• H. the screw is designed to adjust high speeds.
• T. the screw is designed to adjust the idle.

When the engine is drowned out, it is necessary to fully tighten the screws l and h on the carburetor until it stops. Then unscrew for 1.5 revolutions each. Screw t at this stage does not need to touch. After that, you need to try the chainsaw. If everything is done correctly, then it will start right away. We warm up the engine for 7. 10 minutes.

Setting the operating mode at idle. Before adjusting the carburetor, it is necessary to determine the position of the screw L in which the engine speed will be maximum. To do this, you need to slowly scroll it in one or the other. When the position is found, it is necessary to turn the screw counterclockwise at 1/4 turnover.

In this case, you need to ensure that the chain remains motionless.

If suddenly, when adjusting, it started moving, we twist the screw counterclockwise until the chain is stopped. After that, we wind the screw for another 1/4 turnover in the same direction.

The next step is to check the Patriot chainsaw in all engine operating modes. Try to launch a cooled chainsaw and evaluate the work at idle. The revolutions should be equal, not floating. Then try to cut the logs, with the handle of the gas accelerating the engine.

If everything set up correctly, then the engine should work stable, develop power quickly, without failures.

If there are interruptions in the engine, and there is no normal acceleration, it is necessary to scroll the screw L to 1/8 turn counterclockwise and repeat the above manipulations with the screw t. You need to repeat until you achieve the correct operation of the engine.

In order to check the quality of the mixture, we disperse the chainsaw to maximum speed. In the process of adjustment, you must not allow long work in this mode, make pauses. Follow the exhaust and sound of work. Когда из глушителя идет много сизого дыма и звук у мотора очень громкий – значит смесь слишком богатая. Turn the screw H to 1/4 turn counterclockwise and observe the engine operation.

We check the chainsaw at maximum speeds, it should saw well, without failures and interruptions in work

Symptoms of the poor mixture: overheating of the chainsaw engine, interruptions in ignition, a characteristic crack in the exhaust, spontaneous increase in engine speeds. In this situation, it is necessary to turn the screw h by about 1/4 turnover counterclockwise.

All of the above adjustments are carried out until the main conditions are met: the circuit at idle is motionless, the sound of the engine is even, pressing the gas lever leads to rapid acceleration without failures and grabbing. For a more accurate setup of the Patriot 3816 chainsaw carburetor, you can connect an electronic tachometer.

You need to understand that at different times of the year, appropriate adjustment of the Patriot chain carburetor is required. So in winter, when working with a saw, you need to make a mixture richer, t.to. The characteristics of the input air are changing.

What carburetor is on Patriot 3816, its device

The Patriot 3816 chainsaw has a typical carburetor, an analogue of the Chinese “gypsies”. It consists of a light aluminum corps in which there are:

• Throwdoy damper. Thanks to it, the ratio of air in the fuel mixture (dining or enrichment) changes;
• Fuel needle or mixer. Through it, fuel enters the float chamber.
• Diffuser. Narrow area of ​​the camera. Passing through it the air flow is significantly accelerated.
• Float chamber. It is dosed in it and maintained at a certain level.
• The main fuel nozzle. On it, fuel gets from a float chamber into a diffuser.

These are the main nodes of the carburetor of the chainsaw Patriot 3816. In addition to them, there are many more auxiliary small equipment.
