Thanks. I have to go out tonight so I take it apart (again) tomorrow. Unless I get back early.

I'll Tell you Ccfisher,
Now you hit a bad spot with me here.
I ran Accel plugs in the same car I had the 780 on and the plugs would not fire right.
I had just built the engine so my freind and me thought that the cam was off.
Now everything was brand new including the accel plugs.
We took the whole top of the motor apart recheck eveything then put it
back together. It was the same thing all over again seemed like it was running rich and
seemed to be flooding out. So on my buddies sugestion I went to the store and bought
Autolite spark plugs. We installed them and it sounded like a totaly differant engine.
The Accel spark plugs were not firing, I never used them again.
I only use Autolites now. After talking with several other freinds that raced back
then they all told stories about problems with Accel plugs.

Just a note to let you know what I had....Bad PCV valve.

That would certainly do it. Glad you found out what it was.

Well at least it's an easy fix!
