Yes I know about that Bob but thanks for bringing it up. I've spoken with the guy that came up with the idea earlier this summer.
Simple implementation except there is significant percent glow fuel in the gas and the maintenance issues return. The guy claims no carb changes necessary with the fuel concoction he uses, other than fattening needle settings.

I intend to use one of the SAP 180's to do some testing on pipe at some point. It boasts more output than gasoline alone but we'll see. Uses a glow plug and would be simpler all around but at what downsides?
