We never managed to find white gas in Portugal... is that the same as Meths? Anyway... the point is we looked for cleaner fuels for our stove in Europe and eventually gave up and just started using petrol. Been doing that ever since and the stove really doesn't get so jammed up with it, even on cheap Central Asian fuel.
By the way Brock, in Portugal, if you haven't discovered this already, you'll find free internet in nearly every town! Just ask at the tourist bureau where the local community access point is. And do the Serra da Estrela park, near Guarda if I remember correctly. It's amazing.
