Reasons for high fuel consumption of chain saws and elimination methods

1. Carburetor oil leakage
See above for the causes and troubleshooting methods of oil leaks.
2. The air volume holes of each oil system are partially blocked
Reason: The blockage of the air volume holes of each oil system will cause the oil supply of the carburetor to be too rich, which will increase the fuel consumption.
Remedy: Clean according to the aforementioned carburetor cleaning method.
3. The starting thickening device is not closed tightly
See above for the reasons for the lax shutdown of the start-up enrichment device and its elimination methods.
4. The outer diameter of the main oil needle is reduced by wear, and the wear of the main nozzle hole is too large
Reason: The above-mentioned parts are worn out due to long-term high-speed scouring of impurities contained in gasoline during use, which reduces the outer diameter of the main oil needle and the main nozzle hole is too large, resulting in an increase in fuel supply and an increase in fuel consumption.
Remedy: replace with a new measuring hole.
