Gary & Paul,
   At Bensen Days this year, I noticed that Steve McGowens Mazda Rotary
powered Tandem Gyro did the same thing !  It backfired EVERY time he
shut it off !  Someone I was talking to, blamed it on the hot Rotary
exhaust and claimed that there was nothing you could really do about it
!  Funny though, I don't remember Rusty Nance's machine doing it though
!  I'm fairly sure that Steve's machine was carburetted,  but I can't
remember if Rusty's is Carb or Fuel Injected !

Gary, I would suggest an email to both of them.
