Jack Kretmar Posted July 24, 2003 Share Posted July 24, 2003 I have a question about the aircraft conversion for the rotary. You have to add two-stroke lawn mower oil to the fuel. Doesn't this make the engine burn "dirty", thus causing carbon deposit build-up in the combustion chamber and exhaust port areas. My understanding is that enough build-up can cause pre-ignition. Does anyone have information on this? Quote Jack Kretmar Link to comment Share on other sites More sharing options...
