Am I rich?
Posted: Thu Jun 09, 2005 7:49 amMy Sport Cup is doing a lot of "snap crackle & popping" when engine braking. Am I running rich? If so how do I adjust the mixture?

Posted: Thu Jun 09, 2005 9:22 amsounds like the carb deff needs some jetting, or there maybe some debris in the idle circuit. did you put on a pipe with no jetting changes? it is best to get a jet kit than try to set up yourself. not very adjustable carb..

Lean
