Went back out to Advance Auto, bought a can of "Seafoam" fuel conditioner. I've poured it in the tank to let it set awhile.
Also, had to buy a new pair of shoes this afternoon. When I stopped by Harvest Foods for a few items, the tread on my left shoe started flopping. Ripped the rest off and tossed it in the trash.
If it's not one thing, it's another.
