What Causes a Car Carburetor to Leak Fuel?

[VictoriaAnn]

Car carburetor fuel leakage is generally caused by issues such as excessively high fuel level, stuck float needle or float, clogged return fuel line, poor throat tube sealing, or excessive fuel pump pressure. Below is relevant information: 1. A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by engine operation. As a precision mechanical device, it utilizes the kinetic energy of the incoming airflow to atomize the gasoline. 2. Its crucial role for the engine can be described as 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 different operating conditions. To ensure uniform mixing of the air-fuel mixture, the carburetor also has the function of fuel atomization to maintain proper engine operation.
