Arghhhhhh

I have been out mowing, and as I went along, my mower ran rougher and rougher. Backfiring every time I sped up. I stopped the mower, lifted the hood, and smoke is drifting up out of it. Seems some MICE shredded up some paper towels, and built a nest somewhere in the engine housing. I should have realized that because when I started the mower a bunch of little tiny white paper flew out of the front. Now, I have to wait until the engine cools, take a vacuum cleaner and some wrenches out there and see how I can get that nest out. I am so not happy.
