I sympathize with you, Nick.
I had mice take up residence in my snowmobile engine a few years back. They peed in my carburetor and seized it up so badly that I had to cut the casting in half with a Dremel cutoff wheel so I could save the slide and throttle cable.
I wish I would have taken a picture of my snowmobile 3 years ago... opened the hood and couldn't find the engine, it was packed solid with rotting walnuts.
