Conclusion: Lightspeed fires through ugly fouled plugs better than a magneto, just as advertised.  So this might be a benefit in starting if your plugs are somewhat fouled.

Doesn't Lightspeed use an automotive type plug instead of the massive electrode plugs typically used with mags?  I was just wondering if the automotive plug is less prone to fouling.  The Lightspeed probably does fire through better, but unless the plug configuration is the same on the Lightspeed and the mag it seems like the results could be a little misleading.

Right you are Tom, and as Grayhawk noted, plug position counts also.  My Lightspeed fires the top plugs which probably stay cleaner, and the mag fires the lower plugs which are probably dirtier, so my comment was unwarranted.  A comprehensive test would reverse the plug positions and try it again to see what happens.
