Jabiru engines use flywheel magnetos for charging and self energizing
flywheel ignition coils for spark ( Honda M/C IIRC) with fixed advance.
Both very compact and reliable.

That's interesting Dave!
BTW I visited  the chap on the Gold Coast who is developing the Revetec
engine www.revetec.net.au - very interesting development an is a better
engine than the Jabiru,  so some say.

Like most new things these days, someone thought of it before.
I saw a cam driven shaft engine like the Revetec but in radial form, in
the Smithsonian Museum in Wash DC.
IIRC, it was a Lycoming design, and never saw production because all
the money was going to jet development.
