I would always start with 2 turns. put a tach/dwell meter on and adjust for the fastest idle speed. set the ide speed srew and call it good.

About one turn open was usually a good starting point for me.
Eh...wot?

I should have included let it come up to operating temperature to adjust for fastest idle speed

Engine warm, choke open, in park/neutral...screw the idle mixture screw in until it just seats. Don't crank it down or you'll ruin it and it'll never be right. Back it out 1 1/2 turns initially. Start it up and set idle speed. Now crank the mixture screw out slowly, the engine rpm should start going up. If it goes down, crank it in. Keep slowly turning it out as long as doing so raises RPM. At some point the RPM will decrease; at that point turn it back in 1/4 turn. Basically you're trying to get it adjusted to the point where it makes the highest RPM, because that is the point at which the engine is happiest. After you get the mixture set, you'll have to re-adjust idle speed.

If you have a vacuum gauge, plumb it into manifold vac. and adjust to greatest vac. at factory idle speed.

Got it running !! About 2 turns OPEN. Sounds great but that's because there's an exhaust leak !! But hey......... It's running and moves under its own power!! I don't think they call them leaks anymore, believe it is called a tuned exhaust. it running and moving under its own power reminds me of someone of the boonies of Alaska, can't remember who though.
