Kerosene costs four or five times more per gallon than diesel fuel so why would you want to run kerosene. Years ago I had a old John Deere tractor that you would start on gasoline and get it all warmed up and then you would flip a lever and it would switch it over to kerosene. But you had to get the motor warmed up first. Then when it came to shutting it off you switched it back to gas and ran the kerosene out of the carburetor and then shut it off. That's back when kerosene was cheap.
