Working at home is always useful.
About 4:30, I grabbed the w0rNg battery and took it back to the motorcycle shop, and got a new one. Ironically, the smaller battery cost more — WTF? But now I have it and I’ll be ready to ride as soon as it warms up again.
After returning from the shop, I ran a chain down the chimney and it was clear all the way down. I should have known that by the way the sheet I put in front of the fireplace was getting sucked into the chamber. I brushed off some more of the accumulated crud above the damper, shoved the insert back into place, and Mrs. Fetched let 'er rip. Just in time: Winter #5 is upon us, after a rather ugly line of storms yesterday evening. The insert is burning better now than it has in a long time, nice and clean, and it’s warming up nicely in the living room.
Maybe the storms carried the Vortex of Suck™ away with them.
[Holy moly… post #900!]
