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 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.





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 better. My video: 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. automóvil carburador limpio automóvel

Mitch Allread: Don't Call it a Rat Rod... - /BIG MUSCLE
It packs a 400 hp diesel out of a Ford F-350, a Dana 80 rear-end, and a look and feel that would make Max Rockatansky feel right at home. This is Mitch Allread's custom fabricated creation and it is, without a doubt, one of the coolest things on the road today. This is a machine that transcends the traditional hot rod formula by breaking down borders and setting its own stage. Whereas most hot-rods are built by custom shops utilizing parts from mail order catalogs, Mitch took a different approach and fabricated just about everything on his ride by hand. Calling this a rat-rod would be an insult - a work of art however... that'd be just fine.

How to measure and adjust Quadrajet float level
I have had several requests for this, so here you go: 1. The airhorn has to be removed to do this, but the carburetor does not have to be removed from the engine. 2. Some data says to measure from the toe(end that is opposite from the hinge), some say 5/16 inward from the end, etc. I suggest following the specs for your particular carburetor. 3. With the float in the raised position and the inlet needle lightly seated, measure from the top of the float to the top edge of the carburetor with NO gasket in place. If you have to adjust the float, bend at the area that has the cutouts, 4, If you are experiencing flooding issues then it is an excellent time to install a new needle/seat and float and that should cure flooding problems that are not choke-related.
