Well, it looks like the left Mag on Louise's RV-6 is finally calling it quits - best we can tell from the logs, it has 1800 hours since new, and the only things done to it along the way have been timing checks. It has been getting harder and harder to start (ignition key that grounds out the right mag in the start position), and we'd rather not get stranded. I took it off and did an E-gap check (close) and internal visual inspection (looked good) today, but now I can't even get it to time right. I consider these to be 2,000 hour mags anyway, so i figure I'll order a new one Monday morning. A couple of questions came up though thought I'd throw them out to the brain trust...
1) The O-360-A1A has a 4373 on the left 4370 on the right. My TMX-0360 has a 4371/4370 combination, which I thought was standard....but looking up the Unison App table, it calls for 4373/4370. the only difference I can find in on line references is the lag angle 4373 is 20 degrees, 4371 is 25 degrees. Anyone know if this really makes a difference? My Mattituck built engine has preformed exceptionally with the 4371....
2) What would make a mag check fine on the bench for E-gap and point opening, but not do a thing on th e"buzz box" when hooked back up on the airplane? That's what I've got now - "It's dead, Jim....". It bugs me that it appeared to be working a little when I took it off - now I can't get it to do anything.
3) Anyone know of a good deal/great price right now? I need to get one first thing Monday morning - Louise uses it to commute, and I'm gonna lose my airplane if her's isn't flying!
