What Causes a Carburetor to Leak Fuel?

[OLucille]

A carburetor leaking fuel is generally caused by issues such as excessively high fuel level, stuck float needle or float, clogged return fuel line, poor throttle valve sealing, or excessive fuel pump pressure. Below is relevant information: 1. A carburetor is a mechanical device that mixes a specific ratio of gasoline with air under the vacuum generated by the engine's operation. As a precision mechanical device, it utilizes the kinetic energy of the incoming airflow to atomize the gasoline. 2. Its crucial role in the engine can be likened to the heart of the engine. A complete carburetor assembly should include a starting device, idle device, medium load device, full load device, and acceleration device. 3. The carburetor automatically adjusts the mixture concentration and output quantity according to the engine's varying operational demands. To ensure an evenly mixed air-fuel mixture, the carburetor also has the function of atomizing the fuel for smooth engine operation.
