Gasoline does not flow into the chainsaw reason

Gasoline flows from the chainsaw

If gasoline drops periodically appear on the body of the chainsaw, then it is necessary to check the tightness of the fuel tank. Over time, it may dry out. Or the gasket “hardened” and it can no longer perform its direct function.

Why gasoline does not flow in the chainsaw?

Carburetor needle. On cheap chainsaws, the needle in the carburetor often sticks, which prevents fuel from flowing. Sometimes it is enough just to move the needle and insert it correctly.

Oil seals. Chinese and even branded chainsaws may have poor-quality oil seals with poor tightness. Fuel stops flowing when the fuel mixture begins to squeeze out through the oil seals. Gasoline leakage is quite possible through oil seals.

Troubleshooting muffler problems

If at low speeds the engine of the chainsaw works normally, but at high speeds it starts to stall and smoke, the problem may be hidden in the muffler.

To check the quality of its work, you should do:

  • dismantling (with the obligatory closing of the outlet);
  • disassembly (if the muffler is collapsible);
  • cleaning from carbon deposits using special detergents or dry method;
  • drying (using a hair dryer);
  • reassembly and assembly.

Dry cleaning without respiratory protection is not recommended. The carcinogens present in the soot will be released into the surrounding atmosphere as dust, which is extremely hazardous to health if inhaled.

To prevent clogging of the muffler during the operation of the chainsaw, you should carefully monitor the composition of the fuel mixture and the quality of its components.

Why does the chainsaw smoke

Most often, excessive smoke appears when excessive oil is added to the fuel mixture, which does not have time to completely burn out. You should also check if the carburetor settings are out of order.
