Finally got the hard starting problem fixed

[jaylw314]

And it turned out it was just a bad e-gap timing in the left magneto due to cam wear.  It's an IO-360A3B6 with two Slick mags.  The engine was remanufactured, and the mags were new and only have 250 hours on them, so I guess that supports the argument about quality (or lack thereof) of Slick mags.

I thought it was just the cold weather, fine-wire plugs helped for a while but it kept getting worse.  I had dragged my feet getting the mag pulled, since I assumed my A&P would send it out to a specialty shop, and I was worried about the mag getting sent out to a mag shop and being told I needed a new one (after the prop fiasco).  Fortunately, turns out he does to mag work in house.  On today's flight it caught after a one turn.

Anyway, $230 later I have one mag with a 500 hour IRAN done, instead of $900 for an overhauled mag so I call that one a win.

You’ll get to work on it again in another 200 hours.

Aaand, the glass is half-empty

Hope is not a maintenance philosophy.

How old are the mags? I bought a new Lycoming engine 4 years ago and 2 years ago Lycoming called and sent me a new set of mags free saying there was a known issue that was fixed.

They were installed new in 2012 with the remanufactured engine.  It's a couple years off, but interesting.  Thank you for the info!  I'll follow up with my A&P
