The jet (nozzle) would have to be changed for things to be efficient. Getting a set of jets wouldn't be that big of a deal.
That's my first reaction as well. Call me old fashioned, but I stick with optimization for a single fuel. I'm OK with changing nozzles, but running one fuel through a nozzle optimized for a different nozzle gives med bad vibes.
But if you ever did some serious winter travel, you have the option of going multifuel. Pretty cool.

Absolutefantastically!
You're better off using the right jet for the fuel.
Using a jet that is
smaller than spec for a given fuel usually works well, but you just don't get quite as high of output.
For example, if you use a gasoline jet and burn gas, it will work well, but your max BTU's/hr will be a little lower than they would be if you had used the proper jet.
The opposite is generally
not true. Use the above example, but substitute kerosene. The jet will be too large, you'll get too much fuel in the air/fuel mix, and you'll get yellow (inefficient) flames.
