Singer 201 Reverse Sewing Tension Issues
I recently bought a Singer 201 in very good shape, although I am not sure when it was serviced. It seems very clean and I don't have any problem sewing with it in forward, but when I put it in reverse, the bobbin thread becomes very loose and actually forms small loops. Adjusting the needle tension to 0 almost eliminates the problem, but I don't think I should have to adjust the tension when I sew in reverse?
I would appreciate any advice.
Thank you.
