Before you put the rope on, wind the spring counter clock wise until it is tight. The back it off until the hole in the pulley lines up with the hole in the blower housing. Clamp the pulley in place with locking pliers or a C-clamp to keep it from unwinding.
Then feed the rope through the blower housing and pulley holes. Tie a single knot inside the pulley. Release the clamp and slowly allow the spring to reel in the rope. Put the handle back on.
