YES!!! I finally got time to sit down and sew something on my Singer 127 that just came from the shop - and found that the thread take-up spring was broken! I called the repairman, and he said it was fine when he serviced it - and it was, because I have the scrap he sewed on. Sometime, however, the spring broke, and all I had was a nub left. I tried taking it apart, but could not get the old spring out, so I just reassembled the whole thing to take back to him in the morning. VERY frustrating - I wanted to sew some on it tonight!!
I feel like this is something I should have been able to fix. I viewed all the videos in this (and other) threads, and did a search on YouTube for others. Nothing. Rats.
Maybe he'll let me watch when he fixes it - think?
