mmm,.. 201-2 - the potter motor version. You'll love how quiet it runs too. I rebuilt my motor on the living room table (I don't know why... it just happened) and put the motor back on and test drove the machine while we were watching TV. DH suddenly looks over and says: I didn't hear it, I just saw the needle bar and the take up lever moving! No, the TV wasn't THAT loud
That will clean up nicely. I think you said your son fixes machines? Get him to check the wiring on the motor, it's often gooey or cracked. They rewire well and Rain has a good tutorial on VSSMB.blogspot.com
