I was at a yard sale on the weekend and spied a small box half hidden under misc junk. My heart skipped a beat... An Optimus 199 'Oh, an old camp stove eh?" I mused as I carefully opened the box and took inventory. It's been used, and the pot looks like it's been over a fire. The valve key and strap is missing, but the pot holder and mini pump are there. She was asking $20, I offered $10, and it was accepted. I almost skipped back to my truck and drive home as calmly as I could, giggling the whole way. I only have one other Swedish stove: an 8R, but I have some spare gaskets. The old one was crap. Rinsed out the tank, filled with fresh fuel, (Coleman), primed with methanol and away she went. (Still giggling) So the questions: I've been looking into this little marvel all weekend and even dreaming about it. I've read that kerosene burns well in this and maybe better than white gas. Is that true? Kero is cheaper, so I'm thinking of using that. are there any mods that I need to do to run kero? My friend that is very gifted in fabricating is making me a key for the valve, but if one wanted an original, where would I find one? Thanks in advance.
