Rochester Quadrajet Carburetor Rebuild

How to rebuild a Rochester Quadrajet carburetor. For now, this is just a dump of all the remaining pictures I have of the rebuild process (unfortunately a few got corrupted on my failing hard drive). In time I will write the article step-by-step and arrange the photos in a logical order. For now, the photos may be of some help as a reference. Click on any image to view larger.

Hi,
Wow, Great job on your Firebird. Just be careful to replace the power piston spring on your Quadra jet. I placed a Quad on my 67 firebird 326 and had a very poor running engine. This was long before the internet and access to information we have now. It turns out, that since my Quad came from a 400 size engine and with that, every time I stepped on the accelerator A low vacuum would occur and the strong power piston spring would allow too much fuel to be ingested. This resulted in smoke and ultimately cylinder wash. Eventually I stumbled upon a tune up site which mentioned this fact. Mr. Gasket sold a kit with 4 springs and eventually I worked out that the second lightest was best. Although the car ran better, I was still not happy, that is until this summer. I met a fellow through work that had the manifold and Carter afb carb which was the stock setup for a ’67 326ho. I had it rebuilt and can honestly say that I have never been happier with my car and engine!
Good luck !
Glenn
