HSN, 4 turns out from fully closed (screwed in)
Big Screw, tighten all the way in, not too tigtht beware not to damage the o-ring. Then unscrew slightly to make the slot in the screw head perpendicular with the main needle holder. Then unscrew another 1.5 turns.
LSN, this one is set by measuring the distance from the big screw head to the LSN head with a caliper, as if you were measuring the full width of the carburator. You want to get around 47.5mm to 48mm width.
