the mid needle between 1.75-2 turns
high needle 0.75-1 turns in general

really depends on fuel, ambient temp/humidity/elevation, plug you're using, and of course each motor may be a bit different. Oh and pipe too

no carbsmart
if you want to run a carbsmart, get an OS SZ
otherwise, the YS and OS hz don't need carbsmart
