RE: Priming with ether is not strictly neccesary..
Naphta would IMHO be a very good gasoline substitute, where gas without ethanol is not available. It has low octane, evaporates very cleanly, and burns readily. Anyone know the SIT of naphta?
Forget the question. It is 550°C, so the mix relies on the kero to ignite. Gasoline needs only 280°C for self ignition.
