PredatorXX Posted September 15, 2006 Share Posted September 15, 2006 Is it better to run it a little rich? Mine every now and then will blow black smoke then clear up then blow alittle more is it better to run it this way or should I lean it out a little. Air screws at at like 3 1/4 if i am not mistaken. Thanks in advance. Quote Link to comment Share on other sites More sharing options...

Thanks in advance. I have a 97 and have shimmed the needles, advanced the timing, punched the baffles and it began to run lean and pop on decel. I took off the PAIR valve system and backed the needles out 2 turns and it runs great. It sounds to me that 3 1/4 turns is too much.
