Enviro Empress FS (manufactured 12/2005) auger motor was making a horrible sound, so I ordered new parts (auger 50-1346, auger plate with bushing 50-1359, auger collar with screw 50-968, and auger motor EF-001.) The old auger was completely bound up and would not spin at all and was stuck to the old auger plate. When I installed the new parts, when I tighten the 4 screws of the auger plate to keep pellet dust from falling through, the new auger binds and won't spin, but if I loosen the screws until the auger spins, pellet dust falls through and becomes a fire hazard. Any ideas are appreciated. I'm getting tired of throwing money at this thing.
