Unhappy 360 (At idle)

Should idle mixture be set in Neutral or Drive?

Richer = counter clockwise?

For now I just set the idle screws 1,5 turns counter clockwise from full in, it seemed to give the best result.

Tomorrow I will disconnect the brake booster, plug it and see what happens, and do some filming of the engine running with everything attached.

My BMW-employed neighbour says "it's American - they newer where any better than this",
I would very much like to prove he is wrong! :-)
