Depending on what the carb is set like, you may need to richen up the idle screws and then compensate by lowering the curb idle screw until you get a good idle.
Thats what i was thinking too Colbalt. I think the floats are way out (TOO LOW)had this problem not to long ago with a 68 chevelle i had. same symptons floats were adjusted all the way down they had them down so tight i had to take it apart so to adjust them properly. The guy i got it from said it was fine a new one. Later i found out his son had been adjusting on it and could not get it right hmm go figure. What carb do you have? Cole
