Now the tech question.  I seem to recall a timing advance curve for the
rotary that showed all the distributor advance occurring by 3000 rpm. 
If one wanted to build you own ignition system or backup what would be
the concern with operating with a fixed timing equal to the full advance
that occurs at 3000 rpm.  The vast majority of the time would the engine
would be operating at or above this rpm.  What problems might occur from
operating with a fixed ignition timing and being to far advanced at idle
or low rpm? No I'm not trying to recreate a fixed timing magneto.  I'm
aware that Mr Crook has a full ignition package, but am also interested
in other solutions.

It is my understanding that for starting you actualy want to retard
timing.  That is where the impulse coupler gets the nod for two birds,
one stone.  I don't think that the engine would be very efficient, and
may backfire through the intake (Forefire!) in extreme cases.  You may
be able to find some medium for a backup.  Half the advance = limp
home.

It would be easy to test.
