I think I will try jumpering the wires. The switch seems to be right where I rest my elbow doing any work on the pump, poor thing has taken a beating.
I was able to properly adjust the throttle and it has picked up some responsiveness on the low end. Having the throttle stop on the fast idle screw is key, if not you're never opening the pump all the way. Thanks for that post.
