Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I just purchased a Crafstman snow blower from my neighbor that was moving.  I went to use it for the first time and it appeared to be working fine.  When i was getting close to being done with the driveway the unit stopped throwing snow.  I took it int the garage and began to read the manual.  Please keep in mind the neighbor only used this unit two times, it looks brand new.  When i started reading the manual to find out what could be causing this i started to look for the Sheer pins, I cant find them!!  It appears that on the auger there is a bolt and nut by a grease fitting, I am curious if this is where the sheet pins are supposed to be located?  I wonder if the previous owner replaced the break away sheer pins with nuts and bolts.
When i engage the auger it moves very slowly.  I started looking at the pully and when the unit is running and I engage the auger it looks like the auger pully it bent, once it is fully engaged it appears to not be bent, is this normal?  Also the two bolts that attach the pully were very loose so I tioghtned them up.  I need some help so any advice is much appreciated.  Thanks
