You ever hear about boiling them in vinegar? Some guy, maybe about your age

told me about that. That was the first I've heard about that. He said it'll clear everything up...
So, I let the parts soak for about 4 hours each yesterday. When I pulled the float bowl (main body of carb) I saw a bunch of "crud" in metering holes that I didn't get out before. I think this might be the ticket. I also removed the idle mix screws. When I get home toinght Ill go through them with some wire (carefully!) and then blast with some compressed air.
If that doesn't do it, then looks like a Holly will be next purchase unless I can find someone that can do an ultrasonic cleaning.
The CFM of this Q-Jet is 750CFM which seemed like alot to me, sitting on a 4.3 (vortec), until I read why they are all in the 650-750 range. Then, it made alot more sense to me why these things are so incredibly sensitive and tough to work with. So, if I had to go to a Carter or Holly, what CFM should I be looking for? 400-500? Never had to recarb a V6 before
I had one Mopar with this carb and decided never again. Then I realized why I always beat up on GM's

most of them probably ran Q-Jets
