    With that much damage you better tear that motor completely down and inspect that crank really good. With all the metal that was flying around in that cylinder I would be worried about those crank bearings as well.

    Mine looked exactly the same, the reeds even had metal stuck to them. Tear it down and clean everthing and youll find metal everywear.
