I had a local guy rebuild my old Q-jet, it was original on the truck with 230,000kms......

Anyway, I had him tweek it for towing....so he put bigger jets, shorter secondary rods, and removed the Secondary brake mechanism, and replaced everything in the carb.....bushings, float, etc...

All in all it was $300 cash, and all I had to set was the high, and low idle speeds on the truck, and I was off to the races. If you were up here in Ontario, i'd give you his number....

Just my 2 cents, the Qjets are excellent carbs if there tuned/running right. It's the guys that tweek them in there driveways, and have no idea what there doing in the first place that cause there own drivability problems, and blame it on GM, when it's there own problem
