Hmm, I'm wondering if it has been cleaned and oiled recently. Older mechanicals require frequent TLC. Consult your owner's manual for cleaning and maintenance instructions:

Is your sewing machine mechanical (ie, not computerized)??? CAUTION--if your machine is computerized, do NOT proceed with the following suggestions.

If it is mechanical, have you cleaned and oiled your machine recently? Most mechanical sewing machine failures are because they have not been adequately and routinely oiled, the old oil has solidified and frozen the mechanics. I recommend Bernina oil or liquid Tri-Flow Synthetic Lube (or similar good quality sewing machine oil) for mechanical machines--do NOT use 3-in-1, cooking oil, WD-40, or the sewing machine oil from your grandmother's sewing basket. (I am not associated with any Bernina dealer.)

If it is in fact frozen, pick up a bottle of liquid Tri-Flow Synthetic Oil at the hardware store. Oil one or two drops in every oil hole (see your manual) and also every place where metal rubs on metal. But DO NOT oil any plastic gears, rubber, or belts. If it is still stiff or frozen, direct a hot handheld hair dryer into the top and bottom mechanism of your machine. See if that loosens it up. You may have to repeat.

Once your machine is working again, place a drop or two of good sewing machine oil as directed above. Be sure to use a small brush to clean the lint and dirt out of your machine, especially around the feed dogs and bobbin area. (Caution: Compressed air will sometimes force the dirt and lint into areas that cannot be cleaned.) And continue to use good quality sewing machine oil to keep it running. Recommendation: every time you change a bobbin, after 8 hours of sewing, or every six months if it is not in regular use.

it's very possible that the machine could be out of time & needs to
be checked by a sewing machine technican

Make sure that the area is clean and free of lint. Change the needle and rethread the machine.

The balance stitch control on this model is below the stitch patterns; to the far right.

I solved this problem by buying a new Apollo Singer bobbin. It was $12.00 at a local sewing machine store. This bobbin is everywhere, since it goes with about 30 Singer sewing machine models.

I had to do a little adjusting to the new bobbin. 1/3 of a turn loosening the tiny screws.
