Neat cars!

For those of us that aren't great with a carb, where do some of you recommend sending a Q jet for rebuild?

Like North, we rebuild our own Q-jets...they are fairly easy to do, just take your time and follow the directions. You should purchase Cliff Ruggles excellent book on rebuilding and modifying the Quadrajet carb "How to Rebuild and Modify Rochester Quadrajet Carburators" (CarTech Books - SA Design Publisher).

I just rebuilt a recently purchased '69 7029262 Q-jet for my 350HO Custom S this morning and test drove it this afternoon. It's a very straight forward design requiring a little care and patience. Take pictures before and during disassembly to aid in reassembly. There really aren't a lot of parts to deal with. We also have a carb cleaner bucket (5-Gal. bucket that you can get at any auto parts store) that we use to soak the carb parts in for a good week before working on them. It's very satisfying to get the carb running well again. Fortunately, it didn't need anything extreme (like new throttle shaft bushings or leaky bottom plugs) or have any damage.

Speaking of rebuilt Q-jets, we can report that the new 7029262 is working flawlessly after the soaking and rebuild. The secondaries open without a bog and the engine runs clean up to the 5400-ish rpm automatic shift points (don't worry, the aftermarket in-dash tach reads 500-600 rpm high). The shifts were surprisingly crisp and firm and we're running 93 E10 fuel with a slow advance curve in the distributor (36 degrees by 4500 rpm with the factory heavy springs). Not a hint of pinging or detonation and it can burn rubber now! We will play with the advance to bring it in a bit sooner, but it runs great as is for now.

I have a video, but don't know how to modify/attach it (MP4 from Samsung 9 phone).
