The Kerosafe in its glory

Had the Kerosafe burning this evening with its globe on. I got it lit and burning good with the globe off, then got the globe on before it cooled off too much.

These pictures are lousy I know but you get the idea.
I'm beginning to think that this lamp has been converted to burn naptha (Coleman fuel) as its tricky to light and hard to keep lit. Even with the globe on it needs more heat every couple minutes. Granted it was in the mid '50s outside.
I also don't think its as bright as it should be, its maybe as bright as a 40 watt bulb and very yellow. Either the generator is really dirty (a distinct possibility) or somebody has set it up for a lighter fuel. Its got a distinct smell of kerosene when burning (if you hold your nose over the top) which makes me think it may be running rich. Tomorrow I'll drain the kerosene and try it with Coleman fuel. I've heard that since today's K1 is different than the kerosene of yesteryear it may want a 50/50 mix of K1 and Coleman fuel. I'll have to mess around and find out.
