Open the most recently programmed tuning file, then adjust the engine displacement setting by double clicking on the engine disp. text box, changing the value displayed, and Applying. I take off and climb full throttle, full rich mixture and full RPM. After my gear is up, and if noise is a concern, I will reduce my RPM to 2500. I leave my throttle wide open. As I climb I keep my hottest cylinder&x27;s EGT about 1250 - 1300. So after climbing 1000 feet or so, I will lean the mixture. This keeps my hottest CHT under 380 d F. NOTE A rich problem gets worse as the engine heats up. If the throttle is lightly "blipped" at idle, and the rpm drops below the set idle speed, then rises up to the set idle speed, the low speed mixture screws are probably set too rich try 12 turn in, to lean the idle mixture.

When these conditions prevail, even a plug of the correct heat range will overheat. May be caused by a foreign object that. Spark Plug Reading 101. by Mike Canter, Last Updated Dec 19, 2014.
