This video from Sears PartsDirect shows how to replace a recoil starter on a lawn mower. Located on the blower housing, the recoil starter spins the crankshaft to start the lawn mower engine when you pull the starter rope. The recoil starter won't spin the crankshaft if it's broken. If your recoil starter doesn't spin when you pull the starter rope, you can replace it using the steps in this video.
