Thank you everybody! These are all great ideas. My DH is out of town for a couple of days and then I have to leave town for a week, or so. I'll try all of these when I get back. He can check the wires in the foot peddle and other places. He can also help me with taking the motor out. I'm guessing that it's the brushes. The sewing machine is very sluggish to start...I have to help it along with the wheel. Then it may...MAY start moving a little faster, if I keep the peddle down all the way, then it slows back down again.
I've looked over it and I don't see any gunk built up, or fabric/threads tangled. I've cleaned, oiled and greased it. I'll try dripping some oil down into the top of the motor and see what that does. If that doesn't work, I'll take the motor apart. I have a good schematic of it.
