I'm the dumb dodo. We were in Lowes getting a few things (we walked out with nothing), and I needed a little bottle of fuel stabilizer or dry gas for my snowblower, so I can put it away. The guy working there said "I recommend just letting it run empty". So I let it run empty. First I had to engage the drive to bring it down to the walkout basement, and get it up the step-in. No problem, it's running anyway. Now I have it in the doorway of the basement, with the exhaust pointing outside. It should take maybe 10 or 15 minutes, right? After all, it's just got a little fuel left from the last time I used it. So it runs, and I wait. And wait. And wait. Two hours, forty-five minutes. I just don't understand. The entire afternoon was spent keeping an eye on it, and listening to it run full-bore. I'm a dumb dodo.
