Why Replace the Air Cut-Off Valve?

The air cut-off valve prevents lean backfiring and popping on deceleration by momentarily cutting airflow to the pilot circuit when the throttle is closed. A deteriorated or failed valve is a common cause of:

• Popping or backfiring on deceleration
• Rough or inconsistent idle
• Lean running conditions at low throttle

• Air cut-off valve diaphragm
• Associated seals and O-rings
