What's the matter with gasoline entering the motorcycle engine?

[Gabrielle]

Gasoline entering the motorcycle engine is due to a malfunction in the carburetor. Here is the relevant introduction about the carburetor: 1. Definition: The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the engine's operation. 2. Working principle: The carburetor is essentially a tube with an adjustable plate called a throttle plate in the middle to control the airflow through the tube. There is a constricted section in the tube called a Venturi tube, where a vacuum is formed. This constricted section has holes that use the vacuum to draw in fuel.
