Nothing wrong with your line or motor. Last post is absolutely correct. Open the lid, pop off the crank handle (do you know how to use this? I didn't and had to be shown. turn it around and stick the small end into the slanted slot in the drum. there's you emergency handle!).

Anyway, take off the first nut. It is lose, and it only intended to give something to attach the crank handle end to. Then turn the exposed nut 1/8 turn ONLY and try it. It takes very small adjustments to make big changes in speed. Put the second nut back on, slide the emerg handle over the loose nut, and pop the hole in the other end onto the pin on the motor housing, and you're good to go!

should work fine, now.
