I had an 88 P 30 chassis m/h that came with the 86 Q jet engine.
Had dual air pumps but no cat/cons.
It was very lean from the factory. I had to richen it up to pull a trailer up a hill.
Problem then was, I had to lean it out every year for the E-check money grab.
My point here is it could be lean if all original .But being apart at least twice..no telling. That's why i asked about the idle caps.
I agree. Start all over with the right kit and some research as to what it came with.
Good luck , Mr louis chevrolet, if you ever return
