I found an old stove I had pretty much forgotten about down in the basement. A Coleman Peak One model 400-499. White gas model. It has to be 20 to 25 years old at least. I've only used it a few times, very short duration, over the years. It still has the same original tank-full of white gas in it.

This stove is way too big and heavy for modern backpacking, but I wanted to see if it would fire up. With that same fuel that had been in it for those 20-25 years! (Oops - forgot to drain it I guess.)

That sucker fired right up instantly. Settled down in 30 seconds or so. Beautiful well-regulared blue flame. The adjustability was fantastic. You could go from almost non-existant flame to a roaring monster flame, all with beautiful blue color. With very precise control.

Gotta say, I was impressed! So I oiled up the leather seal in the pump, and the O-ring in the filler cap. We'll see how it does in another 25 years! Report to follow ... (for those of us still living on that date).
