I have a Snapper L.E. SINGLE STAGE SMALL FRAME SNOW THROWER SERIES 0 that a friend gave me when he moved. It runs well. The auger rotates fine but does not throw much snow out the chute. What it does throw only throws out next to the blower. Most of the snow comes out of the back of the blower at the bottom. Any ideas. Since I got it for free I am open to spending some money to fix it.
