My machine went crazy yesterday. It started running a thousand miles a minute, al by itself. We were at a retreat and stepped off to the ironing board. Smelled burned too.

This is typical for the "cooked out rf cap" syndrome. Somewhere in the control circuit, either in the pedal or near the motor, there is probably a capacitor to kill rf (radio frequency) noise. You don't need it, and old age ruins it, with exactly the symptoms you describe. They usually look like a AA battery. Locate it and remove it, no need to replace it. Just make sure the other contacts are tight.

I second what steihy said - common and one part that is not needed for the machine to run fine. Removing it is one of those things I've read that is good to do if you are fixing up one of this series even if it has not causing problems.

I had a 301 that I left plugged in and it started sewing by itself! The problem was in the foot pedal. Since I had purchased the machine only a week before, the seller graciously sent me a new foot pedal, problem solved.
But it was freaky when I saw it slowly sewing away with no one there! I now unplug all my machines when I leave the room for more than 5 minutes!

Yep, capacitor. Here's a pic of my wife's 319 foot controller. I haven't removed the capacitor yet. I probably will when we get it here.

It's just held on by the same two screws that hold the cord on.
