I had more to add but was unaware of the limit here. Wonder about adjusting the throttle stop screw also as when its warm the idle isnt all that high. I dont have any tech equipment. I have viewed steppermotor movement when key is turned on. I have a guy who has been a tech all his life says he thinks he could fix it so I think I wiil have him look at it. Would you be willing to email me if I sent you mine. Al
