The step-by-step instructions in this lawn mower repair guide explain how to replace a recoil starter on a lawn mower that has an overhead valve (OHV) engine. If recoil starter rope doesn't retract, it's likely the recoil spring is broken. Replacing just the spring is difficult; the best way to repair a recoil starter is to replace the entire assembly with a manufacturer-approved replacement part.
This repair procedure works for replacing the recoil starter on common Briggs & Stratton OHV engines that power Craftsman, MTD, Husqvarna, Cub Cadet, Toro, Troybilt, Snapper, Murray and Ariens walk-behind lawn mowers.
