I know nothing about the carb in your bike, but every carb I've had my hands on has the standard pilot air/fuel screw setting of between 1 and 2 turns from gently seated to bottom.
The way I set it is to get the bike running at a slow steady idle on the idle adjuster, then adjust the pilot screw until the point where you get maximum idle speed. Re-adjust the idle to a slow steady setting, and re-adjust the pilot to the point where the motor runs fastest. Do this one more time and you should be right.
What the pilot air jet does is introduce some air into the fuel in the needle jet (you should see a few small holes around the side of needle jet tube) which turns the fuel in that tube into an air/fuel foam. This foam is much easier to atomise as it comes up the venturi and hits the airstream in the carb throat.
I think you need to strip and clean your carb again, and see if you can find an in-line fuel filter to fit. A larger filter is less restrictive to the flow. Small ones can let too little fuel through when the level in the tank gets low.
