also to the person that said the apex seals start chattering at 7400rpms... WHAT?? apex seal chatter can be caused by many factors. rpm alone could be one if your winding the ever loving **** out of it. i have taken stock rotating assemblies over the 9k mark. chatter is caused by poor lubrication on the seals, bad balancing, worn bearings, and a few other issues.!

Well, after some local support from BigIslandSevens (third gen and second gen owner) and wfo91rx7 (second gen owner), it finally took off. I still have to recheck the timing, and readjust the carb, but it finally sustaned an idle. I think I'm going to grab some new plugs tomorrow because of all the MMO, ATF, Ether, and gas that were on the old plugs. I'll get a video of the "new" engine when I get time. Much love to my local guys Dave, Josh, Stu, and you too Ray!

I can't express enough how important it is to help each other out. These guys know I always try to help everyone I can. So in my time of need, they pulled through for me. I live my life on the Bo and Luke Duke philosophy. "We don't need money. We barter our way through life".

No problem Sam. I enjoyed it. I don't know much about first gens so it was a good oportunity to learna bit by getting hands on. Not that I did much other than turn a key, pump the gas and try to Zap you with the Dizzy!
Plus When it is all done I may want to buy it,... If the other two we have don't suck us dry first.
I think with new plugs, a carb adjustment and some fine timing adjustments and it will be straight. It had pretty decent response once we got it to fire off and idle.
Still wouldn't start without a little ether help. ( I think due to the plugs and all the MMO residue getting burned off.)
Let me know whenever you want more help. I am ususually open in the afternoons.
You should probabl;y changew the oil too with as much ether and gas was going thr the engine.

Thanks again guys. I took a couple of pics from the tear down. That seal went kicking and screaming. The irons will be ok I think, but the housing and the rotor is trash. I'll let the pictures speak for themself.

Glad to hear you got it back going, to bad you did not sale it a few weeks earlier LOL. Maybe this will give you some insight to the boost you are pushing through your FB, PROBABLY NOT!!!. Well hope i can make it sunday but if not you all have fun.

Well. After all the mixed info about the flywheels, I decided to pull the '81 flywheel back out. Stu and Josh came over last night and the engine came back out. I cleaned all the surface rust off the '84 flywheel and pressure plate. We put it back in with the 215 mm disk. I couldn't get a 225 mm till sometime next week. So here's the deal. If you have a 83-85 12A, DO NOT use a 81-82 flywheel with out changing the front counter balance. Leason learned. I was sure it wouldn't matter. I was told it wouldn't matter. Well, from first hand experiance, I was wrong. So, with that being said, me and Stu put about 25 miles on the SA last night. Actually, it was about 4 am this morning. The engine still sounds like a street port, but the vibration is gone. Stu tooks some pics and video from last night. I'll let him give his 2 cents .

Nice work Sam, I've got to hand it to you you don't give up! I'll be watching for the pictures and video. I always had that 12A from the brown one hooked up in front of stock cats, so it was always real quiet in those days, hard to imagine it sounding like a street port!
