Still trying to find a source for 4mm carbon brushes. A1Sewing, what a jooeke. Other guy doesn't answer email or his phone. To timid to order assortment from China. Where to look next. Maybe that guy near Rome that works out of his home. When I'find them, I'll get a bunch cause Japanese made machines are in my future. (Like negotiating for shop space downtown for sewing and quilting club, am I getting serious or what!)
