I've noticed a couple of posts on this subject, but only one response that made some sense, but it was on an older engine. I've got a 6.5 motor with a 'speed control' throttle lever (like for a lawn mower). I'd like to keep the govenor in the loop to keep my kids from accelerating too quickly and keep their top speed in check. How can I make this thing work? Do I just have to use a real strong return spring to get it back to idle? It is very stiff to move. Thanks
