Singer 27-4 Treadle Tension Problems - Update
Several days ago I posted a request for help for what I felt was a problem with the tension. I found a small amount of dust in the needle channel that goes down along the shuttle. The good news is the machine has been sewing beautiful stitches ever since. Today I filled a new bobbin, changed out the old one and rethreaded the machine and everything is good. Thanks again for your help.
