Bolt the engine on the plane. Take it to the flying field and bolt the wings on to act as a vibration dampener and reduce airframe stress. Start the engine and run 2 or 3 tanks through it at a slightly rich setting. Tune the low speed needle for good transition after a 45 second idle. Tune the high speed needle for peak RPM and then richen about 200-400RPM off peak. Fly it.
