I use my Juwels and Arara 37 and whatnot every few months. I would love a Meva but they dont turn up often here. I think they have the equivalent of "Nur für Benzin" on them too. Once I was stupid enough to fuel up a kerosene burning Primus with Coleman fuel. Ran great as I remember....nothing blew up, and I snuffed it when I realized what I had done.
