We have an old Ariens ST828. It has been a great snowblower, but it seems that age is getting the best of it. The other day it stopped moving forward. We removed the bottom plate and there was a broken spring. We took the broken spring down to the parts store and got a new one. The problem is that since it had come detached before we found it, we are having a hard time figuring out where it attaches. Does anyone have some guidance? It would be very appreciated.
