Aha,
There IS no accurate "how many turns" because each carb is a little
different, and the needle can be seated differently in the plunger.
And, indeed, the cars are pretty tolerant.
Me, personally, I get it so it feels about right, then check the spark
plugs every so often. If they're black, I lean it out a bit, and if
they're too grey, I richen it a bit. Sort of a smooth whitish-grey just
heading towards dark grey is where I'm happy. This helps with balancing
carbs, too, as it shows how each cylinder is doing...
