I have an older craftsman snow blower that runs great and pump snow
perfectly but I have 3 minor issues and I am not sure if they can be fixed.
Sears says they discontinued making the parts. My 3 issues are...

1. The part where the snow flys out of spins from vibration so I have to
hold it so the snow blows in the correct direction.

2. The handle that puts the blower wheels in gear does not stay in place.
It jumps in and out.

3. The tires are bald.

From what I see all the parts are there but I don't know how these parts
originally stayed in place. I took a picture if anyone thinks they can help
or suggest a way to fix this.
