Ok, it's been a while but I finally had time to go check the car out some more. Took the battery out of my truck and cranked and cranked and it wouldn't start so I pulled the plugs and cleaned them (sooty black) and it fired right up. Ran awful though. From idle to 2000 rpm it was pouring black smoke worse than a diesel and was kind of backfiring. After 2000-2500rpm's and up it smoothed out and spun up perfect and purred. I wasn't able to drive it because it didn't have the wheels on it yet. I looked at the vacuum hoses and everything and couldn't find anything obviously wrong. I have a Hayne's repair manual but it doesn't help much at ALL and doesn't even have a vacuum hose diagram in it.

Anyone know where I can start checking for the poor idle? I played with the timing from one extreme to the other and it didn't help much at all, but that was just changing it on the distributor. I have been trying to think of something that could cause it to run so extremely rich at idle but possibly great at 2500+ RPM's. Of course it didn't build boost because of that tore up turbo hose, but the motor spun up great.

I appreciate the help guys.

Thanks for the tip!

Is the regulator on top of the motor, near the injectors? I saw something near the injectors/intake and thought it might be the regulator but wasn't sure and wasn't sure how to test it until now.
