I've had guys tune for me before, only to be left wondering why did he do that? It rocks, but why? What did he see that I didn't. ETC ETC..

Your idle is too low, too rich on LSN, or too Lean.. It can be any of those.. Do the pinch test.. Get it running and Pinch the fuel line as close to the carb as possible. If it revs up before 3 seconds then it is too lean. IF it takes longer than 5 seconds it is too rich.. Also, if it revs right at 3-4 seconds, then it is about right and you need to raise the Idle speed..
