Needle valve
The needle valve determines the fuel/air ratio in the fuel mixture. Turning the needle clockwise will lean the mixture, turning it counterclockwise will enrich it. When starting the engine for the first time, screw the main needle completely in and then open it by two and a half turns. For subsequent starts, leave the needle in the same position as it was during the previous run.
