I fixed the engine monitor so it now shows RPM. Had been running it at real low RPMs. Still, very rough.

Happened to press button 3 (Cancel) on the EM3 (not EC3) and engine started running smoothly (tested up to about 3,000 PRM). Still without prop.

Could be a coincidence, will have to let engine cool down and try again. But first time out of 5 or more runs where it started running smoothly.

Now I need to fix an oil lead at filter adapter and move exhaust pipe away from bottom of fuselage so it doesn't melt it and perhaps put on a prop.
