1. Gather the necessary tools and parts. You will need a replacement starter cord, a screwdriver, and a pair of pliers.
2. Locate the starter cord assembly. The starter cord assembly is typically located on the side of the lawn mower, near the engine.
3. Remove the old starter cord. Use the screwdriver to remove the screws that hold the starter cord assembly in place. Then, use the pliers to pull the old starter cord out of the assembly.
4. Install the new starter cord. Insert the new starter cord into the assembly and secure it with the screws.
5. Test the new starter cord. Pull the starter cord to start the lawn mower. If the lawn mower starts, you have successfully replaced the starter cord.
Here are some additional tips for replacing a starter cord on a lawn mower:
* Be sure to purchase the correct replacement starter cord for your lawn mower model.
* If the starter cord is too long, it can wrap around the flywheel and damage the lawn mower.
* If the starter cord is too short, it will not be able to reach the flywheel and the lawn mower will not start.
* Be careful not to over-tighten the screws that hold the starter cord assembly in place. This can damage the assembly.
