Hello,
This NOT a note bashing Emagair. This is just a service update to let folks like me know what is happening with P/E mags.
Yesterday I had a P mag problem occur at about 25 hours.
I had been flying around for about 3 hours and decided to stop and refuel. After refueling I hung around and shared stories with some others that were there. All total I was on the ramp about 45 minutes. I am telling you this to relate how long the engine and mags were possibly heat soaked. The outside air tmp was about 60 and on the ramp maybe 65 with a breeze and the airplane pointed into the breeze. I did not have the oil door opened.
As I was getting ready to depart I was doing my usual run up proceedure and when I shut off the P lead to the P mag the engine began to run rough. I turned the mag back off and the engine ran smooth, with reduced power on the emag. I turned the p lead back on to the p mag and the engine still ran smoothly so I advanced power and the engine ran rough again. This time I shut down the engine and waited a few minutes to try and reason out what was happening.
I thought that perhaps shutting the p mag off by using the p lead had some how affected the timing so I tried a restart. The engine started fine and ran good at all rpm's so I elected to depart for my home airport about 5 miles away.
Take off was normal and climb out was just fine until at about 2,000 feet the engine once again began to run rough. I looked at the CHT's they were all pretty mormal around 300 or so. I turned off the p lead to the P mag and the engine once again ran smooth so I continued on, I could see my home field now. After about a minute or so I tried turning on the P mag again and it ran fine and the engine performance increased considerablt, of course. I left the P mag on line and landed.
After landing the engine again ran rough and once again I turned off the P mag.
I called Brad this morning at Emagair and he said that this was a new problem for them and to send in the mag for bench testing.
I just wanted this episode to be recorded for future and present users of E/P mags.

approx. 25 hours and I keep finding more reasons to like the RV-9 all the time, what a great little airplane.
