Kero burning Colemans are a very small percentage of those that are out there. You have to seek them out. Partial list: 152, 201, 214, 234, 237, 237A, 249, 639, 639B, 639C
I know that list is incomplete. It seems like a lot of different models but they just don't seem to be that common. 220 Coleman fuel models are everywhere. Coleman fuel around here $13.00 a gallon and up; too expensive for me. 220 gasoline models can be had cheap at yard sales and Craigslist. Kero models, not so much. The 639C is still available NEW. Personally I'm not in love with the stamped burner assembly on that one. Some people love them. If you can find a 237 or 237A they are quality builds.
A 200A Coleman fuel model can be converted to kero with about $20 worth of new parts and they are an easy install. Some people claim they smell but usually it is a J tube in the burner assembly that needs sealing or they are putting too much pressure in the fount (fuel tank) overdriving the mantle. What I mean by overdriving is so much vaporized fuel is flowing to the mantle that some of it actually burns outside the mantle. When that happens I reduce the tank pressure until it burns right, leaving the valve full open. I adjust the pressure in the tank, not the valve. Generally kero models have to be run full on to keep the generator hot enough to vaporize the kero. If you starve them for fuel they cool off after a while and will flare up with a dirty yellow/orange flame from liquid fuel (not vaporized) getting through the system. They need to be run hot to work right. It isn't has hard as it sounds.
I prefer kero indoors but technically you shouldn't burn any of them indoors or a confined space. They consume O2 and put out small ammounts of CO.
The current production dual fuel gasoline models are another option, new or used. They can burn 87 oct gasoline from the pump or Coleman fuel. Pump gas is cheap, cheap, cheap compared to Coleman fuel or kero and you can get it anywhere. I do use them inside some but do the start up and shut down OUTSIDE for sure. Most of the stink is during start up and shut down. I don't think they are that bad when they are up to temp and running properly. Ventilation is your friend.
