How do I replace starter cord on lawn mower?

Remove the engine starter cover or blower housing which contains the starter rope. Check to see if the spring is still good then just rewind the starter rope pulley to re-tension the spring. Insert the replacement rope into pulley as originally routed and let the spring wind the rope back into pulley. Then replace the starter handle. Make sure you keep tension on the starter pulley while the rope is winding.
