On most carbs u should have about 5 settings for the needle. The lower the clip (the higher the needle), the more fuel u gonna get. I dunno what u mean about turning the air/fuel screw around... 4 strokes have fuel screws (anti clockwise = more fuel) and 2 strokes have air screw (anti clockwise = more air). You cant turn them around. Have u taken the carb apart yet to see if the jets are dirty?
