My engine is under 2,5 ccm long stroke engine. With bigger engine, it will not be a problem since the engine has more volume to comprime the air to ignite fuel drops than my engine with little volume.

Same i am not sure how it works with american gasoline, take a research to learn out how it will work in the engine. But probably the gasoline works as a viscosity reduction in the kerosene and make it easier to atomize the kerosene, it is the kerosene who has excellent autoignition compared with the gasoline.

I noticed that fuel consumption is slightly less than the model diesel fuel with ether, but I have not measured to be sure it really is the reduction in consumption.

There is very little difference in compression ratio either fuel has ether or not..
