That Drunk Guy
Yeah the Orange flame and odor indicates less than optimum performance. I love my Origo, I have both now propane and alcohol (two boats) and I have not noticed an appreciable difference in time to boil a kettle of water.The fuel is a brand new can of denatured alcohol "marine fuel," however the stove is used. Perhaps the stove came with some moisture in the fuel area? Or some dirt or something?
I'll fiddle with the stove to see if I can get it burning clean, and then post some more results.
