To know for shure youll have to get a temp gun, my rusty ran best at around 220 and iv heard that you can run them all the way up to 300 (its not recomended though)

1. get your idel set right or the rest will be a pain
2. get your high speed needle set (factory is 2.5 turns out i ran around 1.5-2)
3. low speed needle, this (in my mind) is also the most tempermental part of tuning
