John. Very good to know you found the cause for the problem on the ground rather than high up somewhere. As for the overhaul, I recommend to get yourself the treatment of a O-200 crank with the O-200 STC. from Aircraft Specialties. That gives you a few more horses (than a C-85 crank would give you) without having to change a lot on the Aircraft itself, something you would have to when switching over to a O-200 engine. I wish you good luck.
