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

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.

When it comes to classic hot-rod components, nothing gets people going like a multi-carb setup. And the king amount these is the Tri-power. Long admired for their stellar performance and macho attitude, the tri-power has become a hard thing to find. So why find one? Why not build your own? Today on GEARZ, Stacey walks you through the process of building your own tri-power out of old derelict parts. After that, Stacey pulls out the big Mopar guns and shows what it takes to put together a six-pack. If multi-carbs are your deal... you?re gonna love this show!

Who said gearheads aren't into recycling?





How to adjust carburetor mixture screws
Here's how to find and adjust the mixture screws on your carburetor. Note that metering-block style carbs such as Holley and Demon more often have one or 2 mixture screws in each metering block depending on the number of venturi. Also those may not be located at the bottom of the carb as in factory carburetors.
