What is a carbi on car?

A carbi on a car is a device used to mix air and fuel in the correct ratio for combustion in the engine. It is a type of carburetor, which is a component of the fuel system in internal combustion engines. The carburetor mixes the air and fuel in the correct ratio by using a Venturi tube, which creates a low pressure area that draws fuel from the fuel tank and mixes it with air. The air-fuel mixture is then drawn into the engine where it is combusted to produce power.
