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.

Clean a Carburetor, Without Rebuilding it - This Really Works
Do you have a car or truck with a carburetor. Do you think you need a tune up. Want a cheep fix to make it run better. 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: How to clean a carburetor cheaply and without having to remove it from the engine. This engine has the carter YFA single barrel carburetor on the Ford 300 inline 6. A very good motor but at its age of 240,000 miles it is hard to pass a smog check. To help it pass I spray carb cleaner into the fuel bowl via the fuel bowl vent and this cleans the carb from the inside and the internal parts. This video will show you a handy trick to pass a smog check, and keep your vehicle running smooth. automóvil carburador limpio automóvel автомобиль карбюратор чистый
