I bought this machine for $25. The motor wasn’t working, so we opened it up to clean and see what’s wrong. The wires were all rotten and rheostat needed cleaning and adjustments. One part needed replacement, but I could not find the name for it. I ordered “new” motor from the e-bay and yesterday my husband attached it to the machine with new wires. Machine worked! It is amazing 
The motor came with rheostat which had the part needed replacement. It is a bit bigger, so my husband increased the hole for knee bar attachment in the wooden base of the machine. He also adjusted the bar as it wasn’t horizontal to the floor. Now this Singer just needs cleaning and my daughter can start using it this long weekend
