If you got the 221 Featherweight that was on ebay, it said it doesn't run. You probably need a new foot pedal. They seem to go bad on featherweights. Sometimes, you can take the foot pedal/controls apart and fix it, but usually they have to be replaced.
Most of these machines are very easy to fix. Sometimes the motor has to be rewired, but not a big job.
Good luck, Enjoy the machine
