These components work together to provide the right fuel-to-air ratio for the engine to run smoothly and efficiently.

It is located in the carburetor bowl and is responsible for providing the majority of the fuel needed for the engine to run at high speeds. The size of the main jet determines how much fuel is flowing into the carburetor, and the fuel-to-air ratio can be adjusted by changing the size of the main jet. Pilot Jet: The pilot jet is a small tube that controls the flow of fuel into the carburetor at low speeds. It is located in the carburetor throat and is responsible for providing the fuel needed for the engine to idle and run at low speeds. The size of the pilot jet determin...
