The saw carburetor assembly process is carried out in reverse order. If after this process there is the appearance of smoke from the muffler and the saw engine starts poorly, you need to make sure that there is a spring located under the lever needle.

A spring shuts off the fuel supply. In its absence, spontaneous "overflow" of fuel into the candle occurs. It is important to ensure that the spring is installed in its place, and make sure that the candle is working.

If the candle is poured with gasoline, then it should be dried. To do this, the part is twisted, merged, the excess fuel that has got inside, through the existing hole. The candle dries for more than half an hour. Then it is put into place, and the chainsaw is brought into working condition.
