WA 1972 402 Restored quadrajet 7042206

[John H.]

This is a 1972 402 Chevy and GMC.

I had a few carbs done by a guy who has over 40 years experience rebuilding carburetors and has done thousands. This carb has just been restored and is ready to install. The rebuilding extras include NEW bronze bushings installed in base. ALL rebuilt quadrajets should have this done. The bases are aluminum and the shaft bores wear and cause poor idle and vacuum leaks. All NEW primary throttle plates are installed. They are also aluminum and wear out. The secondary air valve cams are plastic. This lifts the metering rods when the secondary’s open. They wear out or break causing a lean wide open. All NEW air valve cams are used in these rebuilds. New float installed.

The main well fuel plugs are MT13 sealed. Other sealers will not hold up to today’s fuels and will leak. The accelerator pump cups are fluorelastomer and are blue in color. They are the only pump cups that will withstand today’s fuel additives. The black pump cups are no good and will swell or shrink. All NEW choke pulloffs. The secondary throttle plates are DAG213 sealed for a good quadrajet idle quality. The top and body are chemically color bond 420 dichromated.

The aluminum base is restored with a two part cleaning process that brings the aluminum back to the original finish. No silver paint or wire buffing is used. The bottom of base is then machined flat to prevent any potential warpage. The screws and linkage are yellow zinc plated. No rusty parts here. Carbs are tested on their machine that uses a pressure gauge and fuel meter. This assures no leaks and a good pump stream for the accelerator. A mounting gasket and an air cleaner gasket are included. You will not be disappointed.

John, are the needles and jets set for a stock motor or has it been set up for a certain set-up on the motor it was going onto?

Thanks for the info. I'm was just curious.

Mike, I also have a 7042210 regular 350 carb I was going to use on my project, but could use the 7042910 California carb I have listed in another thread and sell the 210 carb.

The 210 carb is dated the 15th day of 72.
