Air Cut-Off Valve Set - Each

The Air Cut-Off Valve Set is a cost-effective alternative to OEM assemblies, designed to prevent "afterburn" caused by a lean fuel mixture when closing the throttle. It achieves this by temporarily closing the slow-jet air passage, enriching the mixture instantly. This high-quality kit includes all necessary components for a complete rebuild, including a diaphragm, spring, and O-ring. Suitable for one carburetor unless otherwise noted.
