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.
Time-Lapse Carburettor Swap on a 1968 Pontiac Firebird
Recently I fitted a second-hand Quadrajet carburettor to my 1968 Pontiac
Much to my surprise the car actually started, idled and ran. Unfortunately
the Quadrajet developed some fuel leaks, however, and ideally needed a
For the duration I decided to put my original Edelbrock carburettor back on
so I could continue to use the car while deciding what to do with the
Quadrajet. That's what you'll see happening in this video.
If you're wondering why I remove the studs after reinstalling them, it's
because I previously had a spacer plate installed which needed long
As a result, when I put the carburettor back without the spacer, the studs
were too long and I wouldn't have been able to bolt the carburettor back
down. I didn't want to use the spacer plate for now, so I had to cobble
together a selection of temporary fasteners.
I'll be getting some properly sized studs in due course...

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
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.

On the Road Again [S8 Ep10 Teaser]
On this episode of Gearz, Stacey hits the road to help out a Gearz Nation
member with his '56 Corvette project. Since the guy really wants to drive
the car, putting in a modern 5 or 6 spd tranny would be really nice. But
which one? Well, we not only answer that question, but also give the guy a
little helping hand with the transmission too. If you've ever wished Stacey
made house calls, this is the show to see. After that we take a look at
some serious questions that people ask about becoming a tool dealer and if
it's really worth it. You wanted to know...we got the answers for you!
