Mark Thanks for the info but you misunderstood my question. The engine is fine its the Ellison that may need attention. The manual talks about rebuilding approx every 5 years or if your experiencing "non-standard" operations. The manual also says you should be able to kill the engine with the mixture. The FAQ's on the website says it runs slightly lean at low RPMs and slightly rich at high RPMS. If it is already lean at low RPMs then going full lean should kill it. It does not. There seems to be a conflict between what the manual and website says and what I am experiencing. I am just trying to understand and resolve this so I understand my level of risk here. I will call Steve today after I remove the cowling and make sure the metering tube is rotating 90 degrees as described in the theory section of the manual.
