See 1976 Chevrolet pickup with Rochester quadrajet upgrade on SBC 350 V8. We removed the hood, mounted a camera looking down on the air horn, and took it for a spin, running wide open on an uphill grade. See how the secondary air valve responds to rpm drop at each upshift of the THM. Also included is a smoking burnout.

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)

how to minimize engine bog with a Quadrajet carb
this is to minimize engine bog when the pedal is to the metal. do not over tighten, very small spring...you want to try 1/4 turns or 1/2...q-jets are good if tuned properly. also when you are tightening screw it will have tension on it so keep the screwdriver firm. 1986 gmc sierra single straightpipe to cherrybomb. you will need a small flathead screwdriver and a 3/32 allen key. be sure not to tighten to much or else your vacuum secondary flaps wont open.





How to adjust Quadrajet secondary air doors
These take some trial and error to get them adjusted so that there is no bog, but it's not hard to do-here's how.





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

Most relaxing sound for men - Old-School American V8 Corvette C3 1979 (Stingray)
Includes Cold engine idle, warm idle and a bit of revving to about 4500 RPM. I decided to create this video since my Vette now sounds quite loud thanks to the Cherrybomb glasspack Exhaust and removal of the catalyst. The Exhaust is basically stock. I think this is one of the most relaxing sounds for men who are into cars and machines :) Engine: 5.7 L (350 cid) V8 L-48 Transmission: Warner 4-Speed Manual My Corvette is generally in very good condition and it has already been restored once in USA some years before it arrived in our country. I got the car in a state where the exterior + drivetrain were fine, but the interior needed new carpet, some painting and several other components in order to look great. I'm now pretty much done with the interior. The engine used to have issues but those were mostly external (bad thermostat housing, bad spark plug wires etc.). By now the engine is a pleasure to drive, but the Rochester Quadrajet carburetor has hard time keeping the pre-selected idle speed and sometimes wants to hold it higher, then lower. It might be also some extra fuel leaking in from somewhere occasionally. There used to be some vacuum leaks but I've taken care of them. Perhaps I will replace the intake + carb with an Edelbrock setup for next driving season. The engine compression has been measured recently and the results were perfect for all cylinders. NB! We will soon try to film the Vette from another car when driving on a motorway. I'm hoping to get some good footage that way.

How to de-bog your Quadrajet part 1
Sorry guys, I got the videos a bit out of order. The Rochester Quadrajet has gotten a bad rap over the years, often called a Quadrabog or Quadrajunk. In fact, this is a great multipurpose carbureter once you understand how they work and what not to do to them. In this clip I introduce you to the Quadrajet and begin explaining the theory of operation of these units. Enjoy!
