Martin, on the positive side at least you are learning how to fix these engines. I kind of wish I knew how myself. It certainly makes the repair go faster if I can do it (RIGHT of course) myself. Maybe I should buy a used one that needs work and start learnen !!!!

It sure makes sense that the wrist pin bearing failure could cause more damage in other places....broken pieces all over the engine. Could you have actually broken a crank and hence the wobbly hub?
