Quadra-Jet Question? Help Please!
Running rich I think...
I have a 1970 C10 with a 350 small block and a 4 barrel Quadra-Jet. The engine and carb are from around a 1981 truck. It runs GREAT, tons of power, it does not burn any oil or smoke. I have not done a compression test on it and it has about 100k miles on it. I have played with the timing and tried a couple different settings. Here is the problem: 1.) The exhaust smells very strong. A very strong CO2 smell. Kind of like a 2 stroke outboard boat motor. Whenever I drive it for 10 mins or more my clothes smell. 2.) There is a black stuff building up on the inside and the ends of the exhaust tips. My experience tells me that the motor is running rich, so i tightened down the two screws on the front of the carb. They are all the way in (tight as they can go). They will not turn any more. I have never worked on a Quadra-Jet and not sure how to tune it or even if I am on the right track. What should I do? PS: Please keep all the "quadra-flood", "quadra-junk", "quadra-crap" comments to yourself. I would most definitely prefer to just go buy a new Holly or Edelbrock, but I don't have the funds right now. What I need is suggestions to fix my problem. Thanks!!!
