Hi! I have a used noma N1028LE snow blower, its auger belt is slipping and the man that sold it to me had it serviced 2yrs before and they put in wrong belt.. Does someone have a manual for this machine or the true belt number.. I've been to 4 places and everytime I came back with one that doesn't fit...I also need the spring number, for the lower guide spring on lower auger pulley.. Thank you all..
