Jay, Maybe the solution is to do what the guy form fleabay said-
quote "hi there....no ....the flywheel is not heavy enough,,,,you could make a heavier pulley"
Maybe that would help with the kickback, as the blade holder that's on a push mower adds to the mass of the flywheel. Havn't looked yet but if there is enough room you could bolt/weld one to the pully maybe on top. Would have to be centered very well or you will introduce a vibration that if bad enough would destroy the engine. Just a thought.
