Yea, I've checked and double checked twice over the plug wires as I've made the same mistake before. Plugs are black as coal, rich and flooded. I took the 'new' carb apart and think it may have been sticking. Had a slight amount of some sort of white crust or mold in the float bowls. Cleaned it out and I'll test it out tomorrow night. This carb is an 800 edelbrock thunder, yes also a bit large but with adjustable secondaries throttled back per advice of edelbrock. Car still won't run right with the 'old' carb, but I guess its possible both were messed up.
