I don't think their that hard to work on. But here is a Great book that I picked up to get me started.: Rochester Carburetors , by Doug Roe. If you know just what info your looking for I could copy it at work and snail mail it to you. :D Latter, Tom. :bowtie: :flag:

not hard at all just toss it in the trash and get a holley :lol: but seriously just like anything else if you get a good rebuild kit and pay attention as you take it apart or better yet get a book they are easy

Pretty easy to work on.All you need is a screwdriver,and some needlenose pliers,and the correct kit to replace everything.And a bunch of carb cleaner.

Car Craft article might help.
All the Q-Jet info on the net I didn't look through this one,hope it helps:)

And a 1/16" roll pin punch for the accelerator pump arm.

Kits are easy to install, but the Qjet has a problem with throttle body wear where the shafts go through. If the wear is excessive, you have a vacuum leak. Here's how to check the wear.

The design specification was a clearance of 0.004 ~ 0.006 inch (4 thousands to 6 thousands) as measured by a dial indicator from the throttle shaft to the throttle body in a direction perpendicular to the shaft. In practice, the "break-point" is 0.009 inch. If the wear is 0.009 or less, leave it alone. 0.010 or greater, install bushings.

Thanks to CarbKing on the Stovebolt Board for the specifications
