Reasons for high fuel consumption of carburetor and troubleshooting methods

1. Oil leakage of carburetor 2. Partial blockage of air volume holes of various oil systems Reason: Partial blockage of the air volume holes of each oil system will cause the oil supply of the carburetor to be too thick and cause fuel consumption to increase. Exclusion method: according to the aforementioned carburetor cleaning method can be cleaned. 3. Starting enrichment device is not closed tightly See the previous section for reasons and troubleshooting for lax shutdown of the starter enrichment device. 4. The outer diameter of the main oil needle decreases after wear, and the main nozzle hole is too large after wear 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 fuel consumption. Exclusion method: replace the new measuring hole
