Thank you again. I took this part off and took it to Ace hardware to see what they had. The guy put some rubber tape around the end of it. When it connects with the big wheel it works. It is the part at the beginning of your horizontal arrow that moves up and down. When I hold that part up it works and it's hard to sew while holding it up. Is it supposed to move like that? This is the first antique sewing machine I have owned. Can you please explain how the part you showed would go on or in? Thanks for your patience.
