• Rearward Needle Valve Angle Relative to Engine: 30°
• Needle Valve Adjustment;
• 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
