^ He's right. Check that motor area thoroughly. Every 201 or 15-91 that I collected 10 years ago or recently bought has insulation flaking off it now. It's just at the end of it's service life and I think all of mine need a complete rewire now, motors & all. Ugh. The power cords are easy as pie, especially if just buy a new cord or cord set and don't do it the more tedious way of rewiring it using cut-up extension cords.
