K&S Carburetor Air Cut-Off Valve Set
K&S Carburetor Air Cut-Off Valve Sets feature OEM styling to provide a quality and affordable replacement over OEM. The Air Cut Off Valve prevents lean fuel mixture (backfire) when decelerating and provides a richer mix as the throttle closes by closing off the pilot jet airway temporarily. Stop that pesky backfire problem with the K&S Carburetor Air Cut-Off Valve Set. Sold in sets for one carburetor.
