    Idle needle factory setting?

    It's very known that to reset the High Speed Needle to factory settings on most RC 2-stroke engines is 1 and one half turns out from closed, and to reset the Low Speed Needle, 1 and one quarter turns out from closed. Question: How many turns out from closed should the big idle needle be?
