I guess I should have removed the PCV setup as you recommended earlier, Bill. I'm thinking it's affecting the exhaust. You said an electrical box plug should work to plug the valve cover end I think.
The carb kit we used didn't have replacement jets so that's what I'm going to hit. The truck has always run rich no matter what adjustments were done. If this doesn't work I'll try and find another carb. So I'm lookin' for "jets" - didn't know the name of them.
Thanks Guys!
