On the community page, go down to the equipment threads and check out the different posts on auger storage. There are two different methods, one is to top off the fuel and add a good stabilizer, like Seafoam or Amsoil Quickshot and run it a couple times during the offseason. The other method is to drain the gas, run it till it stalls and then fog the motor and park it for the season.
In the auger threads, there is a thread called F.O.E.A.O [Faternal Order of Eskimo Auger Owners], there is a Huge cache of info, tips and tricks by Eskimo owners for Eskimo owners ! Good luck with which ever method you choose to go with.
