i have a 536.918200 craftsman snowblower an am in need of a real manual, don't mind kicking a bit for it. but i have a question before we get our 10-12 inches of snow tomorrow. This is a two stage blower and when i pull the auger handle, the main paddles go pretty slow but the second stage part seems to move super fast and feels like a fan in front of the chute, is that how a two stage works? My single stage Gilson moves pretty fast.
