A worn-out pull string can make starting your Craftsman lawn mower a frustrating experience. It may feel weak, snag, or even break entirely, leaving you stranded in your yard. Fortunately, replacing the pull string is a straightforward process that requires minimal tools and effort. This article will guide you step-by-step through the process, from identifying the components to installing the new string, ensuring a smooth and efficient repair.
Identifying the Components
Before embarking on the repair, it’s essential to familiarize yourself with the components involved. Understanding these parts will make the process clearer and more efficient:
1. Recoil Starter Housing: This is the external housing that encompasses the recoil starter mechanism. It houses the pull string, spring, and other components responsible for initiating the engine’s rotation.
2. Pull String: This is the rope you pull to engage the recoil starter. It’s typically made of durable nylon or a similar material.
3. Recoil Starter Spring: A powerful spring located inside the recoil housing that stores energy to assist in the engine’s rotation.
4. Recoil Starter Pawl: A small, toothed component that engages with the engine’s flywheel, transferring the energy from the spring to initiate engine rotation.
5. Recoil Starter Cable: This is a cable that connects the pull string to the recoil starter mechanism. It’s responsible for transmitting the pulling force to the spring and pawl.
Preparing for the Replacement
Before you start, gather the following tools and materials:
- New Pull String: Purchase a replacement pull string specifically designed for your Craftsman lawn mower. The string’s length and diameter should match the original.
- Screwdriver: You’ll need a screwdriver that matches the screws securing the recoil starter housing.
- Gloves: Gloves will provide protection for your hands during the repair.
- Safety Glasses: Protecting your eyes from potential debris is essential.
Step-by-Step Guide to Replacing the Pull String
Now that you have the necessary tools and materials, let’s get started on replacing the pull string:
1. Disengage the Blade
Safety First: Always disconnect the spark plug wire from the spark plug to prevent accidental starting. This is crucial for ensuring your safety during the repair process.
2. Remove the Recoil Starter Housing
Locate the screws: The recoil starter housing is typically secured by one or two screws. Identify these screws, usually on the side or bottom of the housing.
Remove the screws: Using your screwdriver, carefully loosen and remove the screws holding the housing in place.
Remove the housing: Once the screws are removed, gently pull the recoil starter housing away from the engine.
3. Disconnect the Old Pull String
Locate the attachment point: The pull string is attached to the recoil starter cable. You’ll see a small loop or hook where the string is connected.
Detach the string: Carefully detach the old pull string from the recoil starter cable. If the string is severely frayed or broken, you might need to use a pair of pliers or cutters to remove it.
4. Prepare and Attach the New Pull String
Thread the new pull string through the housing: Locate the small hole or slot in the recoil starter housing where the new pull string needs to be threaded through. This hole is usually near the area where the old string was attached.
Secure the new pull string: Once you’ve threaded the string through the hole, attach it to the recoil starter cable using the loop or hook provided. Ensure the string is securely fastened.
5. Reinstall the Recoil Starter Housing
Align the housing: Carefully align the recoil starter housing back onto the engine, ensuring it’s properly seated.
Secure the screws: Use your screwdriver to re-tighten the screws that hold the housing in place.
6. Test the New Pull String
Reconnect the spark plug wire: After reinstalling the housing, reconnect the spark plug wire to the spark plug.
Test the pull string: Carefully pull the new string to ensure it operates smoothly and engages the recoil starter mechanism.
Troubleshooting Common Issues
While replacing the pull string is typically a straightforward process, you might encounter some issues. Here are some common problems and their solutions:
1. The Pull String Feels Stiff
- Issue: The recoil starter spring might be too tight.
- Solution: Carefully loosen the tension on the recoil starter spring by adjusting the spring’s tensioner. Consult your owner’s manual for specific instructions on adjusting the spring tension.
2. The Pull String Snags or Breaks
- Issue: The pull string might be damaged or improperly routed.
- Solution: Inspect the pull string for any signs of wear or damage. If necessary, replace the pull string with a new one. Ensure the string is routed correctly through the housing and securely attached to the cable.
3. The Engine Doesn’t Start
- Issue: The recoil starter mechanism might be malfunctioning or the engine might have other issues.
- Solution: If the pull string is properly installed and the engine still doesn’t start, you might need to inspect the recoil starter mechanism for any other problems. Alternatively, you could have an issue with the engine itself, such as a faulty spark plug, fuel system problems, or a clogged air filter. Consult your owner’s manual or seek professional assistance if you suspect these issues.
Maintaining Your Craftsman Lawn Mower
Replacing the pull string is a simple maintenance task that can significantly improve the performance and longevity of your Craftsman lawn mower. Here are some additional tips for maintaining your mower:
- Regularly inspect the pull string: Check the pull string for wear and tear. Replace it immediately if you notice any fraying, breakage, or stiffness.
- Clean the recoil starter housing: Remove dirt and debris from the housing to ensure smooth operation.
- Keep the engine clean: Regularly clean the engine to remove grass clippings and other debris that can hinder performance.
- Change the oil regularly: Follow the manufacturer’s recommendations for changing the oil to maintain optimal engine performance.

FAQ
How long should the pull string be?
The ideal length for your pull string is about 42 inches. This allows for enough slack to comfortably pull the string without it being too long and getting tangled. You can adjust the length to your preference, but make sure you have enough slack to pull the string without feeling resistance from the cord.
Can I use a different type of string?
While you can technically use other types of string, it’s not recommended. The original pull string is designed to withstand the wear and tear of repeated use. Using a different string could lead to premature wear, breakage, and potentially damage to the recoil mechanism.
What if I can’t find the right pull string?
If you’re having trouble finding the specific pull string for your Craftsman lawnmower, you can always contact the manufacturer or a local lawnmower repair shop. They can help you locate the correct replacement string or suggest alternatives that will work with your specific model.
How do I know if the string is worn out?
If you notice any signs of fraying, cracking, or weakening in the string, it’s time to replace it. A worn-out string can easily break, making it difficult to start your lawnmower. You should also check the string regularly for any damage, even if it appears to be in good condition.
Can I replace the pull string myself?
Yes, replacing the pull string on a Craftsman lawnmower is a relatively simple task that most people can do themselves. Just make sure to follow the instructions carefully and use the right tools. If you’re unsure about any step or feel uncomfortable with the process, it’s always best to seek professional help.
What should I do if the pull string breaks?
If the pull string breaks, you’ll need to replace it as soon as possible. A broken pull string can make it impossible to start your lawnmower. Before replacing the string, make sure the recoil mechanism is in good working order. If there’s any damage to the mechanism, you’ll need to address that issue before replacing the string.
How often should I replace the pull string?
It’s a good idea to inspect the pull string at least once a year and replace it if necessary. The frequency of replacement depends on the usage of your lawnmower. If you use it frequently, you may need to replace the string more often than someone who uses it only a few times a year.
