Determine what may have caused the mag coils to overheat. A common cause for engines equipped with automotive ignition and spark plugs is that the spark plug gap is set too wide, raising resistance which increases with altitude. Use a .018" to .020" gap setting.

I just started flying the plane and I have an issue that popped up with my mags. Mag 2 is getting a 200 drop and the 1 is getting between 80-100. The plane ran well on my checkout but on my first day to solo my run up had issues so I taxied back.

My idle fluctuations were from 300-360 with the manifold pressure erratic as well. The only thing I did was that I installed the longer spark plugs that were BRP’s. I wouldn’t think that would matter but I can’t really tell you how it ran before because I swapped them prior to these flights. I am a new owner as you might have guessed.

I was wondering what you think I should check and look for. I just want to take a look at it and see if there’s something that is obviously wrong. Could this issue be related to mine. My new plugs were set at .020” could have been a hair more beuse I only had the disc that went down to .020”.

What are your thoughts?

Sam,
I addressed these issues in a reply to the personal email you sent me.

I would be as sure as I can be that this is an absolutely "normal" magneto coil problem, and the only solution is to change the coils.
