I'll second that, Joe, I tried to reset my idle when I converted to 5 speed. I did find out that you can get a measure of adjustment on idle if you loosen the three bolts that hold the throttle position sencor and the throttle bell crank. There is just enough movement there that you will be able to adjust about 400 RPMs. Hope that is enough. It worked fine for me. I just plain give up on that throttle adjusting screw on the rear of the pump.
