Sounds like it just needs the wheel readjusted. There’s a screw behind the wheel, on the motor housing that move the motor back and forth. You just gently adjust the distance between the motor and the wheel until it runs, right away, when you touch the pedal. Also, be sure to start with the needle, truly, in the highest position.
i believe graphic instructions for doing both of these things, are on the Featherweight shop website.
