What fuel to use in a "H"?

[Redcub]

I am new to the H model Farmall.
How do I know what fuel it uses? I knew a guy that ran a little AC tractor that used Kerosene all during the war years, but it came that way from the factory. Didn't know that some H's were built like that. Can I tell from the data tag or by looking at a certain part? Its been parked since 1975 in the barn and the P.O. has passed away. Other than how the carb is set up, are there any internal parts that are different? ( head, sparkplugs, intake, timing, etc).
The model is a 1941 according to the S/N on the data tag.

The link below is what clued me in the the subject:

And...is (or was) distilled fuel the same thing as Kerosene(Jet A), White Gas, or something completely different? If I have a distilled H, can I mix gasoline and ???? together to get the correct mixture? Bad idea?
Thanks.

use gas. No matter how it came setup, it will burn gasoline. Our 41 H was a distillate burner, but has not had anything but gasoline in it in 45 years.

Checked to a second small tank, none to be found. Thanks for the info John.

True that. They all started on gasoline.

If your tractor doesn't have the second small tank, or an empty hole in the hood, then it was probably a gas-burner right from the beginning.
