That is not a problem. When the reel turns clockwise its initial movement engages it with the flywheel. After that the flywheel, crankshaft and blade-plate all rotate clockwise with the plastic reel, just as they would if you were starting the engine. However the clockwise rotation of the reel is also resisted by the rewind spring. Ignore the rotation of the engine, just as Joe does in the video: turn the reel clockwise until the spring won't let it turn any further. If you suspect the spring is broken, just turn the reel one turn clockwise and let go, as Joe does initially in the video. If the reel does not spring back anticlockwise when you let go, the spring is broken or disengaged at one end. It might spring back even if it is broken, due to friction, so keep winding it clockwise until it won't rotate any more, and it is trying pretty hard to spring back anticlockwise. It is then fully wound, ready for you to feed the cord through and tie it off.
