Hot Spark Ignition

A friend in Florida rigged up his own non-magneto ignition robbed from a
late-model motorcycle and installed it on his O-200-powered Murphy Renegade.
If I recall correctly he has it set up to advance itself as much as 35
degrees. Any more anecdotes about nonstandard ignition boxes?

I want to use one on the IO-360 Continental. And did you know ---- full
advance timing on that engine is 20 degrees btdc? It doesn't seem right,
does it?

Lightspeed Klaus used to advance timing on his O-200 to as much as 45 deg.
btdc. I wonder if he still does. I was just reading Klaus's
denunciation of the magneto as something of an ancient relic. I think I
agree with him.
