912s magneto question

Postby Frequent Flyer » Fri Jan 23, 2009 9:10 am

Hi guys, yesterday afternoon after warming up the engine (912s) i did a mag check on 4000rpm, i checked the 1st mag, drop was ok and engine running smooth, checked the 2nd and drop was ok but engine running a bit rougher than the other mag. Is this normal?

The bottom row of plugs usally foul up quicker than the top ones, try cleaning or replacing.
