Hello patfat, you are exactly right on those brushes. I been working on this used mixer I got off Ebay for 56 dollars. It ran but I tooK it all apart and cleaned and painted and got some new parts and it would not start. The brush thing is right, one brush upper left and the other one bottom right. I got her fired up and it looks like banana nut muffin time again. Heres one for you.....! You the boss.....
