This is the very first test of my snowmobile that I've built from scratch. It runs pretty poorly (carb needs tuning and fuel tank needs proper ventilation and a bunch of other things..), but it works, despite it being quite cold outside -20*C.
The snowmobile is supposed to be a simple snowmobile for trail use and ice fishing, inspired by the old 70s sleds. No modern aggressive powder machine. Complete build log can be seen here (although in swedish):
