possible reason for high comp in 3 is high carbon build up. I read about a civic that had a static compression of 13:1 (from normal 9.5:1ish) just from carbon build up and ran race fuel until he rebuilt the engine. Speaking of, if you've rebuilt 2 engines already you should have a strong grasp on whats going on because really...an engine is an engine...unless it's a wankel. Ask the car these questions 1) are you getting air 2) are you getting fuel (how long was it sitting aka bad gas) 3) are you getting spark. of course if cam or spark timing are off it may not run as stated previously. check all that and if it still doesn't run suck it up and pull the head.
