I have an engine that revs uncontrollably and does not respond to the throttle control. Has anyone had this happen and if so, what was the problem.
Riding Lawn Mower # 917-272431 with B&S 20 HP Twin Intek Dual Valve Engine. It was working fine and all of a sudden there was a clanking sound and the engine revved uncontrolably. I immediately shut the mower off. On restart the same thing happened again. I made sure that the throttle control was set to the lowest setting and it had no control of the engine. Is there a governor on the engine? Any thoughts?
