The engine ran as bad or worse than before, so that was pretty puzzling. After some head scratching, I asked if I could sit in the plane and start it, which I did. That was when I discovered the owner had the constan t speed prop set on course pitch instead of fine pitch. When I changed the prop setting, the engine ran great!=C2- Problem solved. Thanks for all the input.

I just learned the RV-9A owner had to remove th e right mag due to some sort of interference. I suspect he may not have gotten it back in correctly. We're going to start the engine tomorrow on both mags then see how it runs on just the left mag. Of course, if the engine runs good on the L. mag, then we know the problem lies with the right mag.

You say the ma gs are timed correctly. Is it possible that one of the mags was timed 180 d egrees from top dead center? Stranger things have happened.
