AIR CUTOFF VALVE SET
Here is an inexpensive alternative to the costly O.E. assembly. To prevent "afterburn" generated by a lean fuel mixture when closing the throttle, the cut-off valve temporarily closes the slow-jet air passage, creating an instantly richer mixture. This high quality kit contains only the parts necessary for a complete rebuild (diaphragm, spring and O-ring). One kit needed for each carb.
