What fuel does the primus 100 use?

thanks

Kerosene, with one caveat. The 100 came in several variants, the original being the single riser tube with burner basket dropped on, exactly like a large 96, with the added feature that you could put a roarer or a silent spreader on the burner basket.
Then there were a couple of models of 100 that had conventional U-tube burners.
All of these of course burn kero.
The exception is the 100 with a spiritbrannare, which I have discussed before in a number of threads; it burns alcohol.
I have a couple of kero 100s in addition to the spiritbrannare 100. The ones I have have the single riser tube arrangement; to me, this is the unique feature that makes the 100s particularly interesting. The models with the conventional burner are essentially identical to the Optimus 45 and similar 1 3/4 pint roarers.

Thanks ED.

Interesting that it can possibly burn alcohol.

It it possible to get a kit to convert an kero to alcohol?

Thanks again.
