What Phil is saying makes the most sense. It is however the exact opposite of what the thread "carb tuning" in the tech vault is saying. There it clearly says, and I Quote, "The air screw controls the flow of air into the circuit. Turning the air screw clockwise reduces the air flow and richens the circuit. Turning it counter clockwise increases the airflow and leans the circuit."
The thread in the tech vault may be the culpret here and if so, it may need a swift kick out.
