This carb has never been rebuilt and it the correct number for a 1978 Trans Am. I think I need a new accelerator pump because mine looks really old. Also the check ball seems to be stuck or rusted into place. Ideas? More pics after gap

Have it soda blasted after you finish cleaning. It will get rid of all the crud that the solvent leaves behind.

Interesting, very!
It's been a whole lot of years since I last worked on one of these, I'm going to follow along as your pictures and comments dredge up memories.
The check ball being rusted could cause some problems if it has damaged the seat. Is the seat replaceable?
A small amount of muriatic acid may help you to unstick the check ball and it works good to help clean any residue in small passages caused by the alcohol tainted fuel we get these days, BUT you have to be very diligent about neutralizing the acid with a baking soda/water mix and flushing all the acid away or it can cause significant damage.

I recently rebuilt a carb for the first time. I was very intimidated and took photos, put small parts in labeled bags, printed out a couple of instructions from the web. Hell- I even rejetted it based on some web suggestions. The jets I found installed in the (non stock) carb were all out of wack.
It worked flawlessly post rebuild as far as I could tell.

You'll want to do a couple of things:
1) Google the hell out of Q-Jet tuning. I'm going to assume you're not running thru the old single-cat exhaust, and since the original tune was designed to pass a 1978 emissions test, you're gonna want more fuel.
2) Get an assortment of jets and metering rods. It's possible to make a Q-Jet run well, even run strong, but it's not as easy to optimize as a Holley. Good luck and have fun!
