    Make sure the plane is tied down so you can work on it. Start by turning the needle valve all the way in so you have a starting point and then back it out 2 turns. It should start right away. Now go to full throttle and slowly turn the valve in. The engine will begin to speed up and slowly keep adjusting until you can't get any more speed out of it. Then throttle back to idle and open the needle valve 3 clicks. The engine should run like a top now!! :D
