This replacement starter spring is a genuine OEM model from Husqvarna. The starter spring, also sometimes called the recoil spring or recoil starter spring, is part of the entire starter assembly. It attaches to the fan and flywheel housing and is responsible for helping to retract the starter rope when it is pulled to engage the engine. Over time, the spring can wear out or become twisted. This can cause the starter rope to no longer retract or it can even seize up the entire starter assembly. Replacement of the spring is the only option and this OEM part can provide an exact fit for select engines. This part is designed for use with blowers, edgers, trimmers, and pruners that feature Husqvarna engines and that are manufactured by brands like Weed Eater, Poulan, and Husqvarna themselves. The starter spring is made of durable metal and is sold individually. Always disengage the spark plug and allow the engine to cool completely before beginning and repair projects, and protect the hands by wearing gloves.

This is a coiled rewind spring that fits inside the recoil starter assembly of a string trimmer. It stores the energy needed to retract the starter rope after each pull, allowing the engine to be started repeatedly. Replace this spring if the pull cord does not retract on its own, feels loose, or if the spring is visibly broken or unwound.
