The petrol cutter is spinning at idle

Chainsaw Attitude/Idle Adjustment

Chainsaw stalls at idle speed

Cases are common when the chainsaw stalls at idle. First of all, you need to check the muffler, and, if it is dirty, clean it from exhaust tar deposits. Also on the carburetors of some models, etc., there are bolts with the inscriptions H and L. respectively, rough and fine tuning. By adjusting the bolt L during the operation of the chainsaw in such a way that its speed increases (turn the bolt just half a turn), it is possible to eliminate this problem. Adjusting the carburetor requires the mandatory presence of an electronic tachometer and is a rather time-consuming process. That is why in such cases it is better to turn to professionals.

Chainsaw stalls when tilted

When the chainsaw is in a horizontal position, the fuel pipe lies at the bottom of the gas tank, but when the tool is tilted, the pipe is above the fuel mixture, i.e. in the air. This is precisely the reason that the chainsaw stalls on its side.

The chainsaw starts and stalls. Why?

There are several simple rules for the operation and maintenance of a chainsaw, the observance of which will maximize its service life. Preparing the correct fuel mixture, regularly cleaning filters and periodically replacing parts will save you from having to repair your tool for a long time. If it was not possible to avoid the breakdown, then you can figure out its cause completely independently. This applies to any brands of chainsaws, ranging from the more complex models “Husqvarna” and “Calm” and ending with the simplest models “Makita” and “Patriot”.

The chainsaw stalls immediately

What to do if the chainsaw stalls immediately after starting? First you need to check the presence of fuel in the gas tank. If its level is not enough, then you need to prepare the fuel mixture in strict accordance with the ratio of gasoline and oil prescribed in the operating instructions. Gasoline must have the highest possible octane number, and the required brand of oil, as a rule, is indicated in the data sheet of the chainsaw.

Next, we check the spark plug, as well as the contact of its tip with the high-voltage wire. The gap between them should be no more than 0.5 mm. If necessary, the candle is cleaned of carbon deposits and dried. It is recommended to occasionally replace the candle with a completely new one. The reasons for the tool stalling when you press the gas lie in the fuel filter or carburetor jet. Cleaning the gas filter will not take much time and effort, but it is better to entrust the disassembly and cleaning of the carburetor to the specialists of the service center.

Chainsaw stalls under load

If the chainsaw stalls under load, this may be due to the fuel system or a dirty air filter. Changing the fuel with the correct gasoline / oil ratio or cleaning the air filter are universal solutions to this problem. An improperly prepared mixture of low-quality gasoline and, for example, engine oil is the main reason for the malfunctioning of a chainsaw, including in the case when it heats up and stalls.

Chainsaw stalls at high revs

In the event that the tool stalls at high rpm, there are three parts to check: the air filter, the fuel pump, and the gasoline filter. The air filter must be cleaned, you can even wash it under water and dry it thoroughly. Then it is enough to disconnect the fuel hose from the carburetor and see if fuel flows out of it or not. If it flows with a full stream, the petrol filter need not be checked. If, on the contrary, the fault has been found. The breather can be cleaned with a regular needle, and the filter can be carefully disconnected from the suction hose, cleaned or replaced with a new one. The gasoline pump is checked for wear: if fuel does not seep through it, then everything is fine with it. If the problem that your tool stalls at full speed is due to some damage to the pump, then this part just needs to be replaced with a new one.

To find out, try using a scythe by loosening the gas cap.

If the device works properly in this mode, clean the valve.

over, the brushcutter can stall due to poor fuel flow to the carburetor.

Why, then, does the device start, you ask?

The reason for this is that at first the fuel gradually runs into the carburetor and it is enough to work at increased power.

However, then it is produced and at high speeds the engine starts to stall.

In this case, most likely the reason is air leaks under the rubber pipe connecting the carburetor to the cylinder or its rupture. only works on after cleaning, my trimmer was at idle. The mixture was depleted, resulting in overheating. You can eliminate the cause by changing the branch pipe.

Does the situation depend on the brand of the car

When it’s hard to start a petrol cutter, it is worth paying little attention to fastening the carburetor, adapter and their seals

In order to check the injector, it is necessary to remove the carburetor and disassemble it. To remove, it is necessary to unscrew the two nuts securing the air filter and the carburetor, then remove the air filter and the engine control lever, while disconnecting the choke control rod from the carburetor. Next, you need to pull the carburetor slightly towards you, and disconnect the fuel supply hose.

It is necessary to remove the fuel hose as carefully as possible, and prepare a plug for it in advance, since fuel should come from it.

Having removed the carburetor, it must be blown out and cleaned of dirt, only after that the carburetor can be unscrewed.

It is necessary to unscrew the cover of the main chamber of the carburetor, this is the one on which the compensator is installed on top. Further, using a bolt of 8 mm and a length of at least 50 mm. Knock out the valve.

So what happens to the car

Often everything happens according to the standard scenario: you get behind the wheel, turn the ignition key, and the engine starts its normal operation. But as soon as you take your foot off the accelerator pedal, the engine speed immediately begins to fall. It should be noted that in this situation, the idle speed sensor, as before, produces the nominal number of turns. When working with a load, the trimmer had to be idled for some reason. Under all these circumstances, the idle speed jump, creating a distorted operation of the car as a whole. Due to the detonation of the propulsion system, which occurs against the background of idle jumps, the most nasty, but completely natural thing happens. the motor stops working and the car stops.
