Excellent. I reckon that if you let the stove burn for longer with clean kerosene you will start to get bluer flame. My test is to boil water in a pot and see if there is soot (that comes off with your finger) on the bottom of the pot. Cheers Tony
Tony after reading some old posts from five years ago about making your own flame spreader's and trying different heights, I was amazed by the differences. Right know my two Optimus 100's are sharing the cast iron spreader from Fogas. Both stoves running fine.
