You can start up, idle and run at full power with no timing changes at all on a normally aspirated rotary.  We raced for years on just 20 degrees BTDC.  A NA rotary runs just fine on regular car gas without alcohol. Mix one ounce per gallon of 2 cycle oil to the fuel, or inject same. Idle at 1800 to 2000 RPM to keep the engine above reversal speeds and so preserve the speed reduction box.
For high RPM use, 24 to 27 degrees BTDC is a common setting for racing engines operating above
9,500 RPM. A bit more for drag racers above 12,000 RPM.
A crank trigger with one reluctor and two pickups 180 degrees apart, one for each housing works fine. An MSD or Mallory HiFire firing a double ended coil for each housing. Dead simple. Difficult to get your mind around at first, but then like a light bulb over your head.........bing....there it is. No distributor of any kind is required.

I put up drawings and pictures years ago, and will again if I can find them.

Yeah, still want to advance timing.  Really only need 3 speed settings,
Idle -- does not matter really.  Then full power and cruise speed are
the two that matter.  I am having all sports of grief with Fuel Tech
having spent  $4000 AUD on it.  It is good but as always complicated.  A
carby plus simple ignition will do. The Rotec carby for $800 is so
simple and runs on 5 PSI.  Trigger wheel would be a reasonably simple
change.
