Can anyone please clue me in on how I rewind a the cord on a Tecumseh 4.5 hp lawn mower engine? I've added the new cord but can't figure how to rewind it so that it will retract after being pulled. It's probably so obvious that I'm missing it. Can anyone help?

It's a little hard to be sure not knowing which of many starters Tecumseh has made over the years.

Most that mount on top of the engine you want to wind the spring (pulley) first, then thread the new rope into the housing and pulley and tie off the knot. Wind the pulley in the same direction it will turn when you pull the rope or you'll damage the spring.
