Choke Idle Won't Kick Down!
For those who maybe encountering this little minor problem, or for those
who want to prevent it from happening in the future - well here it is. In
this video I discuss the potential problems that can arise from a sticking

Clean a Carburetor Without Rebuilding it and Save Money
Do you own a car or truck that has a carburetor. Are you trying to get your
car to pass a smog check. Do you think you need a tune up.
Have you noticed that on youtube that other videos show you how to clean
the carburetor choke, but that does not clean anything inside the
carburetor. So the other videos don't really help you make your car run
In this example the Holley 2150 2 barrel carburetor, on a 1979 FORD 302 or
5.0 litter engine.
How to clean a carburetor cheaply and without having to remove it from the
engine. This is a way that I avoided having to rebuild my carburetor due to
it not working correctly. The problem that I had with mine was that when I
gave it the gas it had a dead spot. In other words I'd be going along and
give it the gas and it would cough and stall. A friend showed me that by
only squirting carburetor cleaner into the fuel bowl and running the engine
that it would clean it out.
I tried what he told me to do. I ran about half a can of carb cleaner
through the carburetor with the engine running and then went for a drive. I
got down the road about a mile and entered into the freeway. There was a
car coming fast and I was not up to speed and I gave it the gas and it
stalled like it used to. I put the transmission into 2nd gear and floored
it and that blew out what ever was plugging it up and it has run like new
since. This solved the problem I was having, does it sound like a problem
you have. Give it a try.
If you try this and it works then you have fixed your problem for under 5
dollars, and won't spend hundreds of dollars having a mechanic work on your
car. It also helps if you do this before going for a smog check, it will
help you pass.

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

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
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.
