my lawn mower (walk behind 21") hit a tree stump, blde got bend,put a new blde, dont start, white smoke,help
It is possible that when the blade stopped so abruptly, the flywheel kept going and sheered the sheer pin, (replace sheer pin). If it's not the sheer pin, then you bent the crankshaft, at that point, game over, send the mower to the funeral parlor and adopt another one.
