Hey all, I have a 1979 Rochester Quadrajet carb on my 1980 350, I just rebuilt the motor and am in the process of fine tuning everything. The timing I have figured out, but now all I need help with is adjuusting the carb. Does anyone know how many turns the screws should have. Otherwise I will have to try to adjust them by ear, unless there is another method. I have been told that these are a great carb, but you ave to have them tuned just right otherwise they run like crap. Any help is appreciated, thanks! - Shane
