    Gradually open throttle fully when engine is started.
    Close needle valve 30-45° increasing RPM
    When RPM starts decreasing, close needle valve 60-90°, then open
    slowly 15° per second as RPM increases
    Open needle valve 90° further from point where max RPM is obtained
    Fly model until running in is completed (10 tanks of fuel)
    After running in is completed, set idle around 3000RPM
    Stop engine, close mixture control valve 15°, note idling RPM
    90° opened position from where max idling RPM is obtained is
    optimum mixture control valve position
    Mixture Control Valve Position;
    Never try to adjust until needle valve adjustment is performed
    Open mixture control valve one turn (360°), open & close a few
    times to be sure there is no resistance during throttle movement
    Close mixture control valve 30°
    Rotate throttle until resistance is felt when opening throttle
    from closed position
    Open mixture control valve approximately 90° from this point-this
    is the initial mixture control valve position
