Yup.. mine was re-wicked a long time ago, new flame spreader and seals, and I think it's on it's third jet. Last time I had someone else work on it he was dubious about finding some parts the next time.. apparently the later models had self-cleaning jets, and some of the parts changed. I still have the little steel folding cleaning needle that came with it.<br><br>I also have an Optimus that's the same basic unit with a larger tank inside a painted metal box instead of the brass windscreen.<br><br>>>Converted the fuel cap with an Optimus + pump a long time ago to make self-priming in cold weather easier.<<<br><br>Nah. Real men just squeeze the tank.. seriously, I never had much problem with the priming, so long as I released the vacuum in the tank after it cooled. Even if I forgot, it only took 20 seconds or so to do it with hand heat in the cold, or a Bic when it's warmer. It looked to me like that pump was bound to be a hassle with the windscreen, but maybe not. The old way you only had to remove the windscreen for filling.<br><br>I have an MSR Whisperlite that I use mostly these days, but I used the Svea last summer to melt some lead for casting balls. Still puts out an awful lot of heat for it's weight.. of course, the roar has scared newbies witless at times... it is noisy. And a high center of gravity, with a pot on top.<br><br>The Alpaca is very much like a scaled-down space heater. About a foot tall, it has the tubular wick and an elaborate combustion chamber just like a heater, but with a pot rack on top. I haven't seen heaters by them, but I'd sort of be surprised if they didn' t make them. It's NOT really suited for camping, I wouldn't think- too bulky. The Whisperlite is the multi-fuel model with a kerosene jet if I ever need to use it that way. <br><br>The Alpaca fit in well with my setup, as I decided against an emergency generator and went with kerosene instead- space heaters, stoves, Aladdin lamps, lanterns. Redundant and overlapping systems- there are fireplaces, and a wood stove with a removable internal pot rack and a Peltier-junction fan as well. Candle lanterns and a gross of candles as another backup, but mostly to have something to give to help the neighbors... not much light there, but no learning curve.<br><br>I see that Kirkman is selling a Peltier junction that powers a radio from the waste heat of a kerosene lantern. Why not?
