Actually, I think Colin said someone wrote to him claiming to have warmed it sufficiently by urinating on it. (I seem to recall some advice from my Dad about not using the kitchen as a toilet.) Fletcher said his preferred method was to light a tea bag wrapper underneath it to warm the fuel tank enough that he could open the valve and let the priming cup fill. He also mentioned carrying a small eyedropper; you unscrewed the lid to the fuel tank (breaking any vapor lock from the last use), got a dropper full out, screwed the lid back on (very important!), squirted the fuel into the priming cup, and lit it. I've done it (15 or 20 years ago, when I had a then-state-of-the-art Svea in my 40 pound weekend pack) - it was a lot simpler to do than to describe.

Next time I see the Scout I gave mine to, I may have to mug him and get it back. (Oh, my wife just reminded me: he grew up to become a Navy SEAL and, as she so delicately put it, "he can break you.")
