Paul... back in 98 or so, you visited the gyroplane flyin at Wachula Florida
to see my ship the week before Sun-N-Fun.  At the same show, there was a guy
from England indicating that he used gas to warm his 13b up, then switched a
valve to diesel after a few minutes of hot flying.  He indicated that the
cost of petrol caused him to use this method.  As animate as he was, I never
did get a chance to verify his story.

I missed Wachula Florida by one day this year. Actually drove
down there before going to Sun & Fun. I talked to the guys that
have the hurricain severely damaged DC3 out behind the last hangars :)

I have heard that before. Start on gas and run on kerosene. I suspect
it is quite possible.
