Had a bad engine on a 206 one time, had to change it and by then there was better than a foot of snow when the new engine was ready to run!!
You know those little bitty plastic sleds,about 3' long. You can cut a 2x12 to fit in the bottom and a 2x4 cross ways to keep it from sliding off the tire.When you get going fast enough you raise the nose enough to loose the front sled and then you just fly off the ones on the mains.
Someone told me about this once!
