The sweet hum of your lawn mower is a welcome sound, especially during those long, sunny days. But what happens when that hum is replaced with a frustrating, persistent “click”? A faulty starter cord could be the culprit. Don’t worry, replacing it is a relatively easy task that can be done by most homeowners with a few basic tools and a bit of patience. This guide will walk you through the process, from identifying the problem to installing a new cord, ensuring you have your mower back up and running in no time.
A Brief Overview of the Process:
Replacing a lawn mower starter cord involves disconnecting the old cord, removing the old starter assembly, installing the new assembly, and reconnecting the new cord. You’ll need a few basic tools like a screwdriver, pliers, and a wrench.
Identifying the Problem
Before diving into the replacement process, it’s important to confirm the starter cord is indeed the problem. Here are some signs that point to a faulty cord:
- The engine “clicks” but doesn’t start: This is the most common symptom of a bad starter cord. When you pull the cord, you hear a distinct “click” but the engine doesn’t turn over.
- The starter cord feels loose or broken: A damaged or frayed cord will often feel loose or have a broken spring inside.
- The cord retracts slowly: If the cord retracts slowly or doesn’t retract at all, the spring inside the starter assembly might be damaged.
Troubleshooting Your Lawn Mower
If you’re unsure about the source of the problem, you can perform a few basic tests to rule out other potential issues:
Check the Spark Plug
A fouled or damaged spark plug can prevent the engine from starting. Remove the spark plug, inspect it, and clean or replace it if necessary.
Check the Fuel System
Ensure the fuel tank has fresh fuel and the fuel lines are clear. You can also check the carburetor for any blockages or debris.
Test the Battery (If applicable)
If you have a riding lawn mower with an electric starter, test the battery to make sure it has a good charge.
Disconnecting the Old Cord
Once you’ve confirmed the starter cord is the issue, you can begin the replacement process. Start by disconnecting the old cord:
- Locate the starter cord: The starter cord is typically located on the side of the engine, connected to the starter assembly.
- Disconnect the wire: The cord will be connected to a terminal on the starter assembly. Use a screwdriver or pliers to gently disconnect the wire from the terminal.
- Remove the cover (if applicable): Some lawn mowers have a cover that protects the starter assembly. If your mower has a cover, remove it before proceeding.
Removing the Old Starter Assembly
With the cord disconnected, you can now remove the old starter assembly:
- Locate the mounting screws: The starter assembly is typically mounted to the engine block using screws or nuts. Identify the mounting screws or nuts.
- Remove the screws or nuts: Use a screwdriver or wrench to remove the mounting screws or nuts.
- Carefully pull the assembly off: Once the screws or nuts are removed, carefully pull the starter assembly off the engine block.
Installing the New Starter Assembly
Now that the old assembly is removed, you can install the new one:
- Align the new assembly: Position the new starter assembly onto the engine block, ensuring the mounting holes align.
- Secure the assembly: Tighten the mounting screws or nuts securely, but do not overtighten.
Connecting the New Cord
With the new starter assembly in place, you can now connect the new cord:
- Locate the terminal: Identify the terminal on the new starter assembly where the cord needs to be connected.
- Connect the wire: Gently connect the wire from the new cord to the terminal.
- Tighten the connection: Make sure the connection is secure by tightening the wire to the terminal.
- Replace the cover (if applicable): If your mower has a cover, replace it to protect the starter assembly.
Testing the New Cord
With the new cord installed, test it to ensure it’s working properly:
- Pull the cord: Carefully pull the starter cord to start the engine.
- Listen for the engine to turn over: If the engine turns over and starts, the new cord is working correctly.
- Check for any loose connections: If the engine doesn’t start, double-check all the connections to ensure they’re secure.
Additional Tips and Considerations
- Always disconnect the spark plug: Before working on the starter cord, always disconnect the spark plug to prevent accidental starting.
- Use the right tools: Use the appropriate tools for the job to avoid damaging the components.
- Refer to the manufacturer’s manual: If you have any doubts about the process, consult the manufacturer’s manual for specific instructions.
- Replace the recoil spring (if necessary): If the old starter cord spring is worn or damaged, replace it with a new one. This will help ensure smooth operation of the new cord.
Safety Precautions
- Always wear safety glasses: Wear safety glasses to protect your eyes from flying debris.
- Work in a well-ventilated area: The engine may emit fumes, so work in a well-ventilated area.
- Avoid touching the spark plug: Do not touch the spark plug wire or terminal while the engine is running.

FAQs
1. How do I know if my lawn mower starter cord is broken?
If your lawn mower is not starting, it could be a sign of a broken starter cord. When you pull the starter cord, you should feel resistance. If there is no resistance, or if the cord feels loose or frayed, it’s likely broken. Another sign is if the engine starts and runs for a short time before stopping. This could indicate that the cord is not making a good connection.
If you suspect a broken starter cord, it’s important to inspect it thoroughly. Look for any signs of wear and tear, such as fraying, cracks, or broken wires. If you find any damage, you’ll need to replace the cord.
2. What tools do I need to replace a lawn mower starter cord?
You will need a few basic tools to replace a lawn mower starter cord. These include:
- A Phillips screwdriver: This will be used to remove the screws that hold the starter housing in place.
- A pair of pliers: These will help you disconnect the old starter cord and connect the new one.
- A wire cutter: This will help you remove the old starter cord from the starter housing.
You may also need a small flathead screwdriver to pry open the starter housing if it is stuck.
3. How do I disconnect the old starter cord?
To disconnect the old starter cord, you’ll need to follow these steps:
- Identify the starter cord connections: The starter cord is usually connected to the starter housing and the engine. Look for the connections at the ends of the cord and follow them to their respective parts.
- Disconnect the connections: Carefully disconnect the starter cord from the starter housing and the engine. You can do this by gently pulling on the ends of the cord while simultaneously pressing the connection tabs with your fingers or pliers.
Make sure to disconnect the cord from the engine first, then disconnect it from the starter housing. This will help to prevent any accidental sparks or shorts.
4. How do I install the new starter cord?
Installing the new starter cord is the reverse of removing the old one. Follow these steps:
- Connect the new starter cord to the engine: First, connect the new cord to the engine. Make sure the connection is secure and that the tabs are properly engaged.
- Connect the new starter cord to the starter housing: After connecting the cord to the engine, connect it to the starter housing. Again, ensure the connection is secure and that the tabs are properly engaged.
Make sure the cord is routed correctly and does not interfere with any other parts of the lawn mower.
5. How do I adjust the starter cord tension?
Once the new starter cord is installed, you’ll need to adjust the tension so that it retracts smoothly.
- Locate the spring on the starter housing: The spring is usually located on the side of the starter housing.
- Adjust the tension by rotating the spring: You can adjust the tension by rotating the spring using a Phillips screwdriver. Turn the screw clockwise to increase tension and counterclockwise to decrease tension.
Make sure that the spring is not too tight, as this could damage the starter cord.
