Why Does the Carburetor Leak Fuel?
1 Answers
The reasons and solutions for carburetor fuel leakage are as follows: 1. Foreign matter adhering to the contact surface of the needle valve and valve seat: Reason: The needle valve and valve seat are used to control the fuel intake, and their sealing requirements are strict, with a high smoothness of the contact surface. If foreign matter adheres to the contact surface, it will cause the needle valve and valve seat to seal improperly, resulting in fuel leakage. Solution: Clean as per the aforementioned carburetor cleaning method. 2. Needle valve wear: Reason: During use, the needle valve is worn due to long-term erosion by impurities in the gasoline and contact with the valve seat; the imbalance in adjustment at both ends of the float causes the needle valve to bear lateral force and wear. Needle valve wear leads to improper sealing of the valve seat and fuel leakage. Solution: Replace the needle valve, and users should pay attention to regularly cleaning the fuel filter and using high-quality gasoline; replace the needle valve and adjust both ends of the float to be on the same level.
