So I've got an li150.. With a 175 kit. Stage 4 tuned.
Carb jetted 122 main and 50 pilot. How many turns out on the mix.?

Is it a 20mm carb? Generally it's about one and a half.

LI S3's had an 18mm carb as standard.

What carb is on there? If its 18mm then the main jet is way too big- you need around 105 for that set up.

If its 20mm then I would be looking at a 106/ 108 main

If its 22mm then possibly 118.

Depends of course on your atomiser; slide etc

The correct number of turns will be when the engine responds on and off to throttle cleanly and pulls away from idle smoothly. So 1.5 turns is a good starting point but it could end up anywhere from 3/4 to 2.5 depending on the pilot jet and other jetting. Adjust when engine warmed up and after each small adjustment you need to rev it to clear and then reassess.

Ok so it's just trial and error then.... It's a 22mm deltorro carb.
So what does this screw actuall do?? Out mean So? And in means?

in= weaker less fuel out= richer more fuel its a mixture screw not an air screw
