This is a genuine engine recoil starter cup that is designed for use in several different styles of outdoor lawn and garden equipment engines. This engine recoil starter cup is part of the starter recoil assembly and is used to attach various parts to the engine. The starter cup's primary role is to engage the flywheel when the starter rope is pulled. Although it is made of durable metal, this part can become warped or otherwise damaged over time and with constant exposure to high temperatures. If the part fails to work, the engine may not be able to engage until it is replaced. This engine recoil starter cup is manufactured by Tecumseh and is an OEM replacement part. It works with several models of outdoor power equipment engines, including those in machines from Craftsman, Sears, Lawn Boy, MTD, Troy-Bilt, and Tecumseh. The part is sold individually and does not include hardware. Allow the engine to cool completely and wear gloves for hand protection whenever performing engine repairs. If additional parts of the starter recoil assembly need to be replaced, those will require an additional purchase.
