Ok, I am ashamed to say that N839BG has been idle for a year. But I have drained the old 100LL put everything back together and got it running again.
I have noticed however that below 1500 maybe actually when you get down to 1100 RPM it sounds a little rough. Just kind of a stumble in the normally smooth sound of the engine. I have a Zenith carb with no cockpit mixture control by the way. Plugs where brand new a year ago when I got busy and let it sit. Got a feeling its a little out of time however, I can get a very clean 3400RPM static. Thoughts? Jeff York KR-2 N839BG Lexington, KY http://web.qx.net/jeffyork40/
