Mixture Control Valve Fine Setting

Start the engine as described above, slowly close the throttle, and set the idle speed. Hold the model in a horizontal position and slowly lift the nose of the model up. 1. If the engine revs up, you need to close the mixture control valve and repeat the procedure until the rpm does not change when the model is raised. 2. If the engine runs irregularly or stalls, open the mixture control valve slightly. Repeat the procedure again until everything is fine.
