Air Cut-Off Valve Set - Each

The Air Cut-Off Valve Set is an affordable alternative to expensive OEM assemblies. It helps prevent "afterburn" caused by a lean fuel mixture when closing the throttle by temporarily closing the slow-jet air passage to create a richer mixture. This high-quality kit includes all necessary components for a complete rebuild, including a diaphragm, spring, and O-ring. Designed for use with one carburetor.
