BTW, it's usually the cam that the switch actuator rides on that wears to the point that the switch can no longer be adjusted. Make SURE you always replace the old cam when you replace the switch. I made an old assembly work until the new one came in by (in my case) doing two things. 1. I slightly bent the switch actuator and 2. I put a bit of JB-Weld on the worn cam. After that I could get the switch to make at both idle and at WOT (Wide Open Throttle) but there still wasn't much room for future adjustment in case of wear. Mike
