Function

The air corrector jet controls the quantity of air entering the main circuit of the carburetor. It snaps into the top of the emulsion tube and works in conjunction with the main jet and emulsion tube to provide the correct air-fuel mixture throughout the engine's operating range. The air corrector primarily affects the fuel mixture at higher RPMs and helps prevent the engine from running too rich at sustained throttle openings.
