Success!!!! Thank you. Thank you so much for all your suggestions. I oiled the holes near the handwheel for several days in a row with not much change. So I also oiled near the feed dog. I oiled the bar that moves the needle up and down. I used a hair dryer to warm the machine. I kept at it for all this time. And today for the first time, IT WORKED!
Now I have to work on the belt because it slips. But it works!!!!. Thank you all so much. I almost gave up and was going to look for someone who repairs treadle. But all your suggestions and advice were spot on. I will work on the belt.... maybe I need to tighten it. It was a new leather belt which may have stretched this past week. Once I have it all working, I will post you the before and after pictures. Maybe if I'm really smart, I can figure out how to compress a video to fit for download. If not... definitely pictures.
