During this trip, to my embarrassment, I found that I was without a working stove.
My family was hungry. Breakfast had already been delayed. I sat perplexed, starring at the MSR Whisperlight, trying to figure it out. I used it for dinner the night before. I turned knobs, plunged plungers, but nothing. I could not get compression in the fuel tank.
I asked Ethan about it the next day and he showed me why the fuel tank would not compress. With three swift motions, one of which included applying spit to the rubber plunger valve, the stove was working again. Experience pays.
