Carburettor Air Seal Valve Carburettor Qmb139

CARBURETTOR AIR SEAL VALVE CARBURETTOR QMB139 – fits -> See Vehicle Fitment Tab

Carburetor air cut-off valve.
Due to the air-cut valve, the air supply is slightly throttled when the gas is withdrawn in the carburettor, thereby overfilling the gasoline / air mixture and preventing it from being pushed back into the carburettor. All components are made of high quality precision material in OEM quality.
