That can't be right, unless it was adjusted to make up for a vacuum leak
elsewhere. It's just an air bypass adjustment, to let air go past
without being metered.

Unless I have documentation otherwise, any adjustment screw which I know
is screwed up, on any carburetor or FI system, is always "in till tight,
out 1 1/2 turns" as a starting point. :)
