Skyport is not on the net. Rather than the O-200 conversion let me suggest an alternative. Aircraft Specialties Services has an STC which allows the use of an O-200 crankshaft, pistons and rods in a C-85. Surprisingly the FAA allows the engine to be considered a C-85 even though it has the displacement and compression ratio of an O-200. In my opinion this builds a C-95 which may out perform the O-200 because the ignition timing is not retarded as in an O-200. The cost of this change is about the same as the cost for the propeller required for the O-200. I am not quite ready to make this change but were I to do a major overhaul I would very much consider it. The only down side I can think of at this point is that you cannot have a vacuum pump to run your instruments with this conversion. Call them at 1-800-826-9252 if you want to know more. I
neglected to ask them the cost of the STC. Bob Condon
