Not a vintage machine but,
maybe someone can help me. I have a White Superlock serger that will not sew, it did, but now the handwheel will only turn one revolution, and it will go back the same distance. Since it won't continue to turn, it won't sew. Everything else seems to be moving fine. I don't need it to sew well, tension and all of that, I just need it to work so I can use the cutter. Any ideas or suggestions, or should I just pitch it! TIA
