Best Way to set the idle mix on a 4160

[steve meltzer]

I've seen some people advise to adjust each mixture screw (from 1.5 turns out) to it's max vacuum. This makes sense to me, but on the Holley video (not Holly does Houston), they say to adjust to max vacuum, but that both sides should be equal. I find it hard to believe, that in the real world you could make both sides exactly equal, and that the max vacuum on each side should be your goal. thanx. Basic question, I know, but....thanx steve
