Are you sure it's a miss?? Or is it an occasional "cough"? A "miss" is constant....an occasional "cough" happens every couple of seconds to every 5 - 10 seconds and is caused by have the fuel mix too lean. If it's the latter of the two (which I am assuming it is), you just need to bring your high speed needle (if it has one??) out about a 1/4 turn or so until it smooths out. Good luck.
