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.
here is a technique for re-bushing the throttle shaft without drilling.
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.
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.
Tri-Power - Rebuilding The Carburetors [S2 Ep. 5-1]
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! Then Stacey gets
down and dirty and shows you how to build some simple, ultra strong axle
dollys by using some old scrap metal like the kind laying around YOUR
garage. Who said gearheads aren't into recycling?
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.
1962 Pontiac Catalina 421 Super Duty - Gateway Motorsports Park - Huge Wheelie
Be sure to check us out on Facebook at:
This is a video of an awesome 9 Second, 1962 Pontiac Catalina. This Super
Stock Pontiac was racing in the Nostalgia Drags at Gateway Motorsports
Park, just outside of St. Louis, MO. It's an original 421 Super Duty car
and man do they have it set up right. This thing hooks hard and leaves
straight every time. Definitely nothing wrong with a mid 9 second quarter
mile at 143 mph. I thought you might get a kick out of that huge wheelie he
pulled on the one run. I hope you found it interesting....thanks for
Gateway Motorsports Park

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
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.
