Have done all I know to do , cleaned out cooling fins, fresh gas new filters , plugs ect. Runs and mows great , just hunts idle at low RPM. I have found nothing wrong with the governor springs, cleaned carb with carb cleaner and run thru cleaner , no change. Even tried to adjust the "hidden " screw on top of the carb without change. What am I missing ? Or any other ideas
TIA
