Oh, trust me, I am well versed in the art of PZ30/VM26 clone idle mixture screws. There is a special tool you can buy, but it costs about the same as that Nibbi. You can also order thumb screw style adjusters, which at least give you the ability to turn it without unbolting the intake every single time.
If you can access it, I assume that means you uncapped it? The TT250 idle mixture has a cap covering the screw so people can't adjust it (EPA bullcrap). If yes, what have you tried up to this point?
As far as what to set it to. The normal starting point is 1 1/2 turns out from lightly seated. Since it is a fuel screw, more turns out - richer, less - leaner.
