The starting cord is wound around a spring-loaded hub that is designed to engage with the engine flywheel. When you pull the cord, the flywheel rotates, which in turn rotates the crankshaft and moves the piston. A magnetic coupling on the flywheel causes the spark plug to fire cyclically as the piston moves,.
How does a pull cord assembly work?
The operator pulls the rope’s handle or grip. This causes the rope to unwind around the crankshaft and spin it. The spinning motion of the crankshaft cranks the engine. The crankshaft’s motion engages the flywheel, enabling the engine to start.
Why is my pull cord not catching?
The pull cord mechanism on a lawn mower isn’t complicated, and the reason your cord isn’t catching is that one of the components of the flywheel starter assembly has failed under the stress of regular use. Typically it’s either worn or broken pawls, or a damaged pulley system.
