AIR CUT OFF VALVE SET CARB., CARBURETOR. 16048-413-004, 56-1003

K&S Technologies Carburetor Air Cut-Off Valve Set

This K&S Technologies 56-1003 carburetor air cut-off valve set is engineered as a direct OEM-style replacement for the air cut-off valve found on compatible Honda carburetors. It is specifically designed for applications utilizing a non-tapered spring. The air cut-off valve is strategically located on the side of the carburetor. Its primary function is to prevent a lean fuel mixture that can occur during deceleration, commonly known as backfire. It achieves this by temporarily closing the pilot jet airway as the throttle closes, ensuring a richer fuel mixture during this transition.
