RE: E85 in the OS Bio-Ethanol engines
He's thinking of the Enya Gasoline glow plug engine.
It's been done with E85 and regular hot glowplugs. Just get several plugs and try, even four stroke plugs in a two stroke. Good luck. They don't import the BE engines to the US. I thought the oil in OS bioethanol fuel was castor, but maybe it's some synthetic.
