How to measure and adjust Quadrajet float level
I have had several requests for this, so here you go: 1. The airhorn has to be removed to do this, but the carburetor does not have to be removed from the engine. 2. Some data says to measure from the toe(end that is opposite from the hinge), some say 5/16 inward from the end, etc. I suggest following the specs for your particular carburetor. 3. With the float in the raised position and the inlet needle lightly seated, measure from the top of the float to the top edge of the carburetor with NO gasket in place. If you have to adjust the float, bend at the area that has the cutouts, 4, If you are experiencing flooding issues then it is an excellent time to install a new needle/seat and float and that should cure flooding problems that are not choke-related.





Rochester 2-Barrel M2MC Carburetor Jan 15, 2011
Taking on the project of resurrecting a Rochester M2MC 2-Barrel carburetor for a vehicle a friend will be using in a demolition derby in February. The M2MC was brought forth as an economy oriented carburetor intended for smaller displacement engines in the late '70's - actually only a few years! GM kinda cheated on this project by using the front half (primaries) of a Quadrajet carburetor. The primaries on a Quadrajet are very tiny, meaning high air velocity, in conjunction with a metering rod system and triple venturi design assure top fuel efficiency. It comes at the expense the engine, especially the V8 offerings, would be a little restricted in the higher RPM ranges. In all honesty, the public had all but given up on 'performance' during that period. This particular example appears to have suffered from a little water getting into it while it was sitting off of a car a while ago. It will be cleaned before assemble with new gaskets, then adjusted after it is reassembled.

Quadrajet air leak fix and warped air horn repair tutorial.
How to identify a Quadrajet with a warped air horn without diss assembly or running it on a car. These tips would have saved me time and money which is why I made this video. I also discus how to repair a warped air horn and prevent your air horn from warping in the first place. If you have a whistling noise just off idle then you got some work to do. You will never get your engine tuned right, your cold start performing or decent fuel economy unless your four barrel carburetor is just right. Special thanks to Cliff Ruggles for his book Rochester Quadrajet carburetors and to my brother Adrian who spent hours on tuning and fitting. See this video for description of the technique I used to straighten a warped air horn. http://www.youtube.com/watch?v=l_SgQiVf3_0&feature=youtu.be here is a technique for re-bushing the throttle shaft without drilling. http://rmcavoy.freeshell.org/Q_Jet_bushings.html

New quadrajet set up
New air-gap manifold and custom/rebuilt q-jet. Sounds good but I still need to set the timing on the distributor and the carb is tuned already. Hope you like, nothing to fancy just a few revs and walk around...the Exhaust is true dual no x/h pipe and it has cherry bomb glasspacks(3 inch)
