Nice Lois! I would start by running it without the bobbin case in it. Try to peek inside the motor at the communicator. It is the copper thing that the brushes ride on. Is it black, does it spark a lot when you run it? Did you check under the needle plate and slideplate for excessive lint? Does the machine turn over easily with the handwheel? Is the belt too tight? Make sure you have oiled it everywhere you should.
I would start with these.
