Am I the only one that can't get the outer cover off of the stator cover? The ()&@$#%_ phillips head screws - true to form - are absolutely frozen in place. I've splooted 'em with PB Blaster, backed that up with acetone, put a screwdriver in the slots and tapped them with a hammer...no movement at all, even with an electric drill on low power (high torque). The flame thrower (propane torch) will be next, but is there a secret to these that I'm missing? Thanks in advance!
