Topic: Lemony Rotary Rebuild, hard starting, won't idle
I need to reach out to the rotary guys for a moment with a problem I can't seem to wrap my head around.
After blowing up two motors in our 88 RX7, and finding the 3rd junkyard motor wouldn't build compression I got fed up and decided to sell the car. No one would buy it. So I got more fedder up and starting tearing down motors to see what I had. The first two motors where pretty much junk, but the third one I took apart looked darn good. So I decided to rebuild it. I'm reasonably intelligent, I have youtube, and a credit card. So using a Rotary Aviation rebuild kit I went to work.
The irons weren't lapped, they were just lightly sanded to "hone" the surface, per what some guy said online once. All new hard seals were used as well as soft seals. Much blood was shed. Much cursing was, uh, cursed. But the motor eventually went together. After putting the motor back in the car, it wouldn't crank for anything. Double checking everything, I realized I had "stabbed" the CAS wrong. Once that was corrected, I could get it to almost crack over. Thinking it might be a poor compression issue because of questionable housing/irons and new hard seals I put a little oil in the spark plug holes and it cranked. It ran but missed terribly, which led me to double check wiring and I found I had swapped an injector plug on the wiring harness. With that corrected as it stands now, the car will only crank with a little oil in the spark plugs, it runs but wont idle.
My thought is that the motor just needs to run awhile to, for lack of a better term, bed in the seals. But I wondered if there was something else I should check before I give myself lung cancer starting this thing full of oil every time.
