Carb. idle screws are set so thew vehicle idles they are not set at a specific number of turns. With the screw turned out but still in the carb start the vehicle. Let it warm up then turn the screw in until the engine will just idle. There are other adjustments that may assist are to the pilot fuel/air screw. This should be screwed all the way in until it lightly bottoms then turned out 2 turns to start. Once the bike is idling per above turning this screw until it idles at the highest point. This should be between 2 and 3 turns out. Readjust the idle screw to the lower idle if needed and you will be ready to go.
