REFLECTOR: new electronic ign.

[Brian]

Mags do not have a lousy spark. They need two spark plugs per cylinder
because it is too big to combust properly with only one ignition point,
especially a 540. And you need two ignition units because anything can
and will eventually fail. Electronic units fail instantly instead of
running rough like an old style mag.  bg

While I agree that mags are much more failure prone than an EI and that
one of the reasons for two is redundency in case of failure.

Mags have a lousy spark and you will not get full power with just one. 
two are required.  Even with EI's two plugs will provide a more complete
burn and more power than one.
