I hope someone can help me. I have a Craftsman 5/22 snowblower, pretty old but still in great working order. We just got hit here in NJ with 2 ft of snow. Worked fine for 4 houses I helped, including mine (Thanks God). But all of a sudden the the auger wouldn't engage. I checked the belts and noticed that the auger belt was worn and thought that was the culprit. I was able to change out the belt, but now the auger vibrates and makes a loud clanging noise and I have to immediately stop the engine. When I have the auger engaged and the blower tilted back, the vibrating lowers a little but once I release slowly the vibrating and noise starts. I took the unit apart and was able to spin the impeller and the auger smoothly. So I am very confused? Is it an adjustment? Did I not install the belt correctly, does it need an adjustment? PLEASE HELP !
