Snowmobiles like a lot of things have a lot of flammable stuff, if your engines running hot due to lack of cooling snow or dirty carbs it may not blow the engine but the exhaust can and will get very hot, glowing in some cases, hence why on some they wrap the exhaust can in insulation with a heat shield over it Mice, unfortunately, don't mind fiberglass. I have an old 440 fanner that blew the fan belt it got so hot it was dieseling with no spark just running off the heat of the engine the y pipe out of the engine was red hot. I replaced the fan belt and its still running strong 10+ yrs later with no rebuild.Wow....not a good day. Sorry you had that happen.
I've always kind of wondered if the nests would actually start a fire.
I used to flip the hood open just to scan for nests, but I never really looked way down behind stuff. After running the sled for a bit, I could usually smell cooked mice though.
