3. With the model‘s nose positioned high (60 to 90 degrees up from the ground) the engine should not become too lean but may increase in rpm slightly from the setting in step 2. In the nose high position, the mixture should not lean past the „peak“ setting.
3. With the engine running at full throttle, carefully raise the nose of the model to an angle of about 60 degrees. The mixture shouldn‘t get too lean, but you should hear a slight increase in speed. This is normal. If the engine stalls or loses speed when the model is nose up, the mixture is too lean and the needle valve needs to be opened slightly. The engine must always emit a clear trail of gray smoke when running.
