15 91 isn't picking up bobbin thread
I bought a very nice Singer 15 91 from an estate sale last summer, and have been patiently waiting to get it up and running. Had the wiring replaced and some other stuff. As far as I can tell it's threaded right and the bobbin is would correctly.
Problem is, I can't get the upper thread to pick up the bobbin thread. Any suggestions? I feel like I've run 25 out of 26.2 miles in a marathon preparing to operate this thing with joy. But without the bobbin thread working, i can't cross the finish line.
I'm a novice . This is my first vintage machine, but I really want to sew on this one!
