Did you lean the engine after startup ? With my 85HP and the 100LL I always have to lean it on the ground. Didn't do it once and at 1800 RPM on runup it was rough on the mag. I leaned her way out, run it up to full RPM for a minute or so and it cleared the fouled plugs right up. No problems since then.
In CAP we always require our pilots to lean on the ground due to many fouled plugs. Good luck.

I have a newly charged battery (since it now appears that my alternator is not working). Just a few laps around the pattern will allow me to see if I can meet the requirements for a short field landing. The Coupe fires up but it seems a little rough. Turn the radios on, and sure enough, I get a discharge registered on the amp meter. Check ATIS and finally the morning gloom has burned off. Ask ground control for clearance to taxi to 29R with Zulu. I get clearance via Alpha and Joliet. Good, the radio works. In the run up area, I start my engine run up. At 1,500 rpm, the engine is running rough, very rough. This can't be! Tomorrow is my check ride (the flying part)! Maybe if I run it up again a little faster, it will smooth out. No such luck. I guess the only bright spot in the day is that I have the wisdom to call to get permission to taxi back and call it a day. What have I done wrong? I can't seem to get a break! Sorry for my wining.
