1972 GMC Q-Jet, Rebuild? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So my Grandpa's 72 GMC (350/TH400) is having carb issues. My plan is to tear the Q-jet apart over spring break and rebuild it, and do new cap/rotor/plugs/wires, but my question is where is the best place to get a rebuild kit/instructions for the Q-jet? The only other carbs I've worked on have been on B&S small engines, super simple carbs.

FWIW, the issue is it won't idle, period, and it doesn't want to go down into drive. I'm going to inspect/replace vac lines, but it definitely feels like more of a carb issue.

Thanks guys.
