The satisfying “thwack” of a lawn mower pull cord, followed by the roar of the engine, is a welcome sound for many homeowners. But what happens when that cord refuses to budge, or worse, snaps? This article will guide you through the process of repairing a Craftsman lawn mower pull cord, step-by-step. We’ll cover everything from identifying the problem to sourcing replacement parts and mastering the repair process, ensuring you’re back to mowing in no time.
Understanding the Issue
Your Craftsman lawn mower pull cord is a critical component of the starting mechanism. It’s designed to spin the engine’s crankshaft, ultimately igniting the combustion process. When the pull cord malfunctions, it can be due to a variety of reasons, including:
- Broken Spring: The spring that retracts the pull cord can break or weaken, making it impossible to pull the cord.
- Worn-Out Cord: The cord itself can become frayed, worn, or even snapped due to overuse or improper handling.
- Stuck Recoil Assembly: The recoil assembly, which houses the spring and cord, can become jammed due to debris or wear, preventing the cord from retracting.
Getting Started
Before you begin, it’s important to gather the necessary tools and parts. Here’s what you’ll need:
- Phillips screwdriver
- Flat-head screwdriver
- Adjustable wrench
- Replacement pull cord (if needed)
- Replacement spring (if needed)
- Work gloves
- Safety glasses
Step-by-Step Repair Guide
1. Disconnect the Spark Plug
- Safety First: Always disconnect the spark plug wire before attempting any repairs on a lawn mower engine. This prevents accidental starting and potential injury.
- Locate the Spark Plug: It’s typically found on the top of the engine, near the cylinder head.
- Remove the Wire: Carefully pull the spark plug wire off the spark plug terminal.
2. Inspect the Pull Cord Assembly
- Locate the Recoil Assembly: This is usually located on the top or side of the engine, near the pull cord handle.
- Assess the Cord: Check if the cord is frayed, worn, or broken. If so, you’ll need to replace it.
- Inspect the Spring: Examine the spring for any signs of breakage or weakness. A worn-out spring will need to be replaced.
- Check for Debris: Look for any debris or obstructions that might be jamming the recoil assembly.
3. Remove the Recoil Assembly
- Locate the Recoil Cover: This is typically a metal or plastic cover that holds the recoil assembly in place.
- Remove the Screws: Use a screwdriver to remove the screws securing the recoil cover.
- Lift the Cover: Carefully lift the cover off to expose the recoil assembly.
4. Replace the Pull Cord and/or Spring (if necessary)
- Remove the Old Cord: If the cord is damaged, carefully remove it from the recoil assembly.
- Install the New Cord: Thread the new pull cord through the recoil assembly according to the manufacturer’s instructions.
- Replace the Spring: If the spring is broken or weak, replace it with a new one. Ensure the spring is properly installed and tensioned.
5. Reassemble the Recoil Assembly
- Replace the Cover: Carefully replace the recoil cover and secure it with the screws.
- Reconnect the Spark Plug Wire: Reconnect the spark plug wire to the spark plug terminal.
6. Test the Pull Cord
- Pull the Cord: Gently pull the pull cord several times to ensure it retracts smoothly and the engine turns freely.
- Start the Engine: If everything is working properly, you should be able to start the engine.
Troubleshooting Tips
- If the cord doesn’t retract: Check that the spring is properly installed and tensioned.
- If the engine doesn’t turn: Ensure the spark plug is properly connected and that the recoil assembly is not jammed.
- If the engine starts but runs poorly: Check the fuel and air filters for blockages.
Maintaining Your Pull Cord
- Regularly inspect the cord: Check for any signs of wear or damage.
- Lubricate the recoil assembly: Apply a light oil to the recoil assembly to prevent rust and ensure smooth operation.
- Avoid pulling the cord too hard: Excessive force can damage the cord or spring.

Conclusion
By following these steps, you can repair a Craftsman lawn mower pull cord with confidence. Remember to prioritize safety and use the correct tools and parts. A properly functioning pull cord ensures a smooth and efficient mowing experience. For more complex repairs or recurring issues, it’s best to seek professional assistance.
Frequently Asked Questions
1. Why does my Craftsman lawn mower pull cord feel stiff or hard to pull?
The most common reason for a stiff or hard-to-pull cord is a build-up of dirt, debris, and oil. Over time, these substances can accumulate in the recoil housing and around the spring, creating friction that makes it difficult to pull the cord. Another possible cause is a worn-out or broken recoil spring, which can lose its tension and make it harder to pull the cord.
To resolve this issue, you can clean the recoil housing and spring using a brush and compressed air. If the spring is broken or worn, you’ll need to replace it. You can find replacement parts at most hardware stores or online.
2. What if my Craftsman lawn mower pull cord doesn’t recoil properly?
If your pull cord doesn’t recoil smoothly, there could be a few reasons. One common reason is a broken or worn-out recoil spring, which can lose its tension and prevent the cord from retracting properly. Another possibility is that the recoil mechanism itself is damaged or dirty, preventing the cord from returning to its starting position.
To troubleshoot this issue, you can first try cleaning the recoil mechanism and checking the spring for damage. If the spring is broken or worn, you’ll need to replace it. If the recoil mechanism is damaged, you may need to replace it entirely.
3. What if the Craftsman lawn mower pull cord breaks?
A broken pull cord can be frustrating, but it’s a relatively simple fix. First, you’ll need to remove the broken cord from the recoil housing. Next, you’ll need to purchase a new pull cord, which can be found at most hardware stores or online. To install the new cord, simply thread it through the recoil mechanism, attach it to the engine, and then secure it with a tie-wrap or zip tie.
Make sure to choose a pull cord that is compatible with your model of Craftsman lawn mower. Also, be sure to handle the new cord carefully to avoid damaging it during installation.
4. How do I know if the problem is with the pull cord or the engine?
The easiest way to determine if the problem is with the pull cord or the engine is to try starting the mower with a different starting method. If the engine starts easily with a different starting method, then the problem is likely with the pull cord. If the engine still doesn’t start, then the problem is likely with the engine itself.
You can try using a different method to start the engine, such as using a jump starter, if available. If the engine starts with this method, then the problem is with the pull cord. If the engine still doesn’t start, then the problem is with the engine itself.
5. What if the Craftsman lawn mower won’t start at all?
If your Craftsman lawn mower won’t start at all, it could be a problem with the pull cord, the engine, or something else. First, try inspecting the pull cord to make sure it’s not broken or damaged. Then, check the spark plug to see if it’s sparking properly. If the spark plug is faulty, replace it with a new one. Finally, check the fuel system to make sure there’s enough fuel in the tank and that the fuel lines are clear.
If you’ve checked all of these things and the lawn mower still won’t start, you may need to take it to a qualified mechanic for further diagnosis and repair.
6. How can I prevent future problems with the Craftsman lawn mower pull cord?
To prevent future problems with your pull cord, make sure to regularly clean and maintain it. This includes cleaning the recoil housing and spring to remove dirt and debris. You should also inspect the spring for wear and tear, and replace it if it becomes damaged.
Another way to prevent problems is to avoid pulling the cord too hard or too quickly. Pulling the cord too forcefully can put stress on the spring and recoil mechanism, leading to premature wear and tear.
7. Is there any way to lubricate the Craftsman lawn mower pull cord?
While it may seem like lubricating the pull cord would help, it’s actually not recommended. Lubricating the cord can attract dirt and debris, which can then build up and cause problems with the recoil mechanism. It’s best to keep the recoil housing and spring clean and dry to prevent these issues.
Instead of lubricating the pull cord, focus on keeping the recoil mechanism clean and the spring in good condition. This will help ensure smooth operation and prevent future problems.
