Pull the flywheel off and check the flywheel key. As long as you don't have any air leaks around the carb and it's adjusted right, a sheared flywheel key can cause this. They are only about $0.50 at a repair shop.[A href='http://www.wheatfarm.com'][img src='http://www.wheatfarm.com/actractor/flywheel_key.jpg'][/a]
