What is the reason for continuous oil leakage from the carburetor drain port?
2 Answers
The reasons for continuous oil leakage from the carburetor drain port: 1. The fuel inlet valve in the carburetor is stuck by foreign objects, preventing it from closing completely, resulting in an excessively high fuel level and oil leakage; 2. The dynamic balance system of the carburetor fuel inlet system is disrupted. Here is more information about the carburetor: 1. Hazards of oil leakage: Carburetor oil leakage not only increases fuel consumption and affects overall vehicle performance but, more importantly, poses significant safety hazards to the vehicle, requiring timely resolution. 2. Working principle: The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine's operation. As a precise mechanical device, the carburetor utilizes the kinetic energy of the incoming airflow to achieve gasoline atomization.
Last time my motorcycle carburetor was leaking fuel and it took me a long time to figure out the problem, which turned out to be with the float chamber. It could be that the float was stuck or had a small hole, causing the fuel level to rise continuously, and the fuel would spill out through the drain pipe. Another possibility is that the triangular needle valve controlling the fuel inlet was worn out and couldn't seal properly. I remember once when I took it apart, the sealing gasket at the bottom of the carburetor had aged, and gasoline was seeping out directly. In such cases, it's best not to continue riding. Fuel leakage near a hot engine is extremely dangerous. You should immediately take it to a mechanic to have the carburetor disassembled and thoroughly inspected, and replace any worn-out seals as necessary.
