Ran my IO-390 today for the first time! Started on the 3rd blade. However it was not without problems.
1. Ran very, very rich. Had to lean the mixture a lot just to get it to idle. Was able to richen the mixture as RPM's increased but had to lean it again once I began reducing the throttle. Does anyone have the procedure for adjusting the injector mixture?
2. Hartzel prop would not cycle. I think I ran the engine long enough to fill the prop cylinders with oil, but I'm not sure. When attempting to cycle the prop, nothing happens. RPM was about 1600 at the time. Any suggestions?
3. No manifold pressure indication. However I believe this is an instrument problem rather than an engine problem. Dynon Skyview HDX system.
