Parts for Briggs & Stratton 090102-0129-01: Blower Hsg, Rewind Assy Parts

Firing up the lawn mower should be a simple act: hold down the safety bar, grip the hand pull, and yank the rope. What if nothing happens? The pulley works by tightening the spring, then letting it loose, creating compressed air and fuel at the same time the magneto fires the spark plug. It is rare to have an issue with the pulley spring assembly that starts the chain reaction and results in the engine coming to life, but it is possible for the part to fail. If there is a problem with the starter mechanism then it is typically the rope pull wearing out. Users will know when the pulley assembly isn't working either because there is no resistance when the rope is pulled or pulling the rope results in no compression (the engine doesn't sound as if it's turning). When it is determined that the pulley spring needs to be replaced, the user should examine the pull rope and handle to make sure those items do not need to be replaced as well. The most important consideration in replacing this part is to make sure the replacement is an OEM genuine replacement part, which will exactly match this pulley. The pulley is compatible with Cub Cadet and Briggs & Stratton engines.
