How Does A Lawn Mower Pull Cord Work?
The engine’s flywheel is engaged by pulling on the starting cord, which is wrapped around a hub with a spring within. When the cord is pulled, the flywheel rotates, causing the crankshaft to rotate and the piston to move. The spark plug is triggered to fire cyclically by a magnetic connection on the flywheel, which in turn drives the piston.

Bent Or Broken Cord

Recoil Spring Issues
A worn, loose, or damaged recoil spring within the starter assembly is a common problem. The cable may not retract or may lose tension if the recoil spring is defective.
It’s possible that the pulley the cable is coiled around is broken, worn out, or jammed and causing the starter rope not to work.
Starter Assembly Malfunction
It’s possible that the whole recoil starter assembly is broken. due of things like using old parts and shoddy construction

Step 3-Access the Spool and Cord
Now that the starter assembly is off, you can get to the old pull line and the spool. It is usually part of the system and has a housing or cover around it.
Step 4- Unwind and Remove the Old Cord
