Does your Craftsman have a metal chute on it (the part where the snow flies out) I have a 8 hp snowblower but it had a plastic one and it shattered this winter. Of coarse I had some of that stuff that can fix everything laying around:
Mine is an all metal chute, it does pop off some times if your at an extreme angle left or right.
Pops back in so no real issue. Only draw back to mine is its hydrostatic drive so it takes a while to warm up before you can get it to move. Once its warmed up I can rock it back and forth to dig out some pretty good piles though.
Oh and one other thing, its LOUD, louder than most, I wear ear plugs to operate the beast.
I don't own a snowblower. Never did. :( Even when I lived half my life in Northern Ontario I used a good old ArmStrong floating shovel from Canadian Tire. Elbow grease kept it from stalling on cold starts.
