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 Adjust the Choke on Rochester Carburetor By Hopkins
This video shows how to set the Automatic Choke on a Rochester Carburetor with a 350 (small block) chevy Engine,





Rochester Quadrajet, the results!
Two mishaps, the first shown here, the choke coil I got was wound backwards, it made the choke butterfly wind up TIGHTER as the engine warmed up. I swapped on the one from the old carburetor fast enough, the second mishap made me feel like a crud and what did I mess up later that evening. The car would not start leaving the Etobicoke -Queensway show. It was not getting gas. We got it running by priming the carburetor, and boy, was I ticked at myself. In the end it was not my fault it looks like. The new accelerator pump umbrella and rod was a very poor and frail design, the umbrella came detached and stayed at the bottom of the of the pump well, and was a distressed mess. The maker will get a note from me. The upshot? The old assembly went in, all is perfectly fine, the slight tip-in hesitation is gone now too. Stupid lack of pride it seems these days making parts for even simple things like an old carburetor.

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!





How to de-bog your Quadrajet part 2
The Rochester Quadrajet has gotten a bad rap over the years, but it's actually an excellent carburetor once you understand how they work. Often referred to as "Quadrabog" or "Quadrajunk", many of the issues these units suffer stem from neglect, or "modifications" that do more harm than good. Being a spreadbore, air-valve secondary design, the Quadrajet is capable of flowing 750 or 800 cfm of airflow, eliminating the need to buy different carburetors when your set-up changes. In addition, the small primaries make for great drivability and fuel economy. In this clip, I'll discuss theory of operation on the secondary side, since that's where most problems arise. So, leave your preconceived notions at the door and let's see what makes these carburetors tick.





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 HP for $40.
A GEARHEAD PRODUCTION. Throw away the Edelbrock and the Holley and save your money. You can build a hp QJ for less, and get better performance and mpg too.

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.





750 vs. 800cfm Rochester Quadrajets-how to tell them apart
There exists a ton of misinformation regarding the actual airflow capacity of the Rochester Quadrajet. Not many people know how many variations there are or how to tell them apart. Here is a simple video explaining how to identify each size based on casting design. I will cover the "cfm-limited" carbs in a separate video.
