Did you look closely at the mating surfaces when you had the head off for places where water could be leaking into the cylinder(s)? Any signs of water or rust in the cylinders? 65PSI does not seem too far off from normal readings. You mentioned testing spark with a home made tester, how about buying one/two of those inline spark testers (only a few bucks at HF), so you can monitor spark performance while running. Did you drain/refill the gearcase yet?
