Andy, whilst I applaude your lateral thinking here I just can't see the point since you either have to prime an etherless fuel with ether anyway or you have to carry around a heat gun and its power source in order to get the engine to start, and then still need the starter anyway!

Wouldn't it just be simpler to use an ether based fuel mix and be done with it?

I accept that far less ether has to be used when using an etherless fuel run but Istill harbour doubts that the oil will be totally miscible in the kerosene without it.
This excellent link provides good reading concerning model fuels and in part states that a vegetable based oil like castor will NOTblend with a parrafin based fuel.

So perhaps Klotz Benoil has some additive that would assist here?

Cheers.
