Air Cut-Off Valves
Air Cut-Off Valve Sets An inexpensive kit as an alternative to the coatly OEM 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. Included in these kits are the parts necessary for a complete rebuild (diaphragm, spring and o-rings).
