Well, it runs. Lessons learned:
- Use a checklist. For some reason, I decided that because I wasn't going flying, I didn't need to use a checklist. Well, after twice trying to get the engine to start, I realized I should probably turn on the ignition switches. Also, after doing a complete ground run (including a minute or so at high RPM to cycle the prop), I realized I had the Lightspeed breaker pulled (the other side is a mag). I thought it sounded a little rough, but thought it could be the preservative oil on the cylinders or something else. Inexcusable, really, to not have all this stuff checked out ahead of time. On the plus side, I was surprised how well it ran on just one mag.
- Be sure of the tachometer setting on the EMS before starting. I thought it should be 3, turns out it's 1.5 (for the Dynon on the p-lead), so I was getting 1/2 the actual RPM displayed. This, combined with the rougher running, caused me to run a little faster than I'd have liked. CHTs maxed out at around 300, so thinking I'm probably okay.
- Had a flame shoot out of the exhaust when I turned off the mag (to do the "mag check", before I realized the Lightspeed was off). Guessing this is the unburned fuel/air mixture in the exhaust.
It was far from the perfect first engine start I'd hoped for, but I'll take it, given everything else works.

Don't worry Rob. Mine was far from perfect either. Turns out the wiring diagram for my ignition was off and had me put the wrong ignition system to ground. I too have a mag and a Lightspeed, but the wiring diagram didn't have me grounding one out for start. According to the other mechanics on the filed I should run the mag used to start to the ground. going to review my schematics today. Congrats. I wonder who will be the next to get their first flight.

Thanks, Eric... my money is on you, since my DAR visit isn't scheduled for almost a month.
Is your mag an impulse coupled mag? I'm starting mine on both ignitions--we'll except for that first start
BTW, added a couple videos...
First start, on one mag: http://www.youtube.com/watch?v=ImWsEK9Fhuc
Starting it later on both ignitions: http://www.youtube.com/watch?v=XfLZDNbsdrk

My mag is impulse coupled. Started with the lightspeed disabled on the first run. The second run had them both enabled, although the key switch grounds out the Lightspeed in the start position, but as soon as I release it and I am in the both position there is a noticeable smoothing of the engine. I like the videos. My airport manager filmed my first run on her iphone. and she hasn't been able to send it to me yet. I am looking at my first flight on February 6th or 7th. I'll see how the re-assembly goes. I am also changing the upper cowl faster from the hinge to the Skybolt fastners, so there is a days work.

Has anyone had a kickback issue (or any other issues) starting with both lightspeed+mag on the (I)O-540?
