You’re out in the yard, ready to tackle the overgrowth, and you go to start your Briggs & Stratton lawnmower, only to find the pull cord doesn’t budge. Or maybe it does, but the engine doesn’t even sputter to life. It’s a frustrating experience that can leave you staring at your mower in despair. But don’t worry, a broken pull cord is a common problem and easily fixable with the right tools and a little know-how. This guide will walk you through the process of replacing your Briggs & Stratton lawnmower pull cord step-by-step, ensuring you get back to mowing in no time.
The pull cord is an essential part of your lawnmower’s starting system. It’s connected to the recoil starter, which uses a spring mechanism to spin the engine crankshaft, enabling the engine to start. When the pull cord breaks, the connection between you and the starter is lost, and you can’t engage the starting mechanism.
Gathering Your Tools and Parts
Before you dive into replacing your pull cord, make sure you have the necessary tools and parts on hand. Here’s what you’ll need:
- New pull cord: The most important item! Ensure you get the correct length and type of pull cord for your Briggs & Stratton lawnmower model. You can find replacements at your local hardware store, home improvement center, or online.
- Phillips screwdriver: This is for removing screws holding the recoil starter assembly in place.
- Flathead screwdriver: You may need this to help pry off the recoil starter cover.
- Wire cutters: These are handy for cutting the old pull cord.
- Gloves: These will protect your hands while working with the spring-loaded recoil starter.
- Optional: WD-40 or a similar lubricant: This can be helpful for smoothing out the recoil starter mechanism.
Identifying the Pull Cord and Recoil Starter
The pull cord is the rope that you pull to start your lawnmower. It’s attached to the recoil starter assembly, which is located under the engine cover or near the top of the engine. This assembly contains the spring, gears, and other components that power the engine’s initial spin.
Inspecting the Recoil Starter Assembly
Before you start the replacement process, it’s a good idea to take a moment to inspect the recoil starter assembly. Look for signs of damage or wear, such as:
- Cracked or broken housing: This could indicate that the recoil starter is old and worn out.
- Stripped or damaged gears: These can prevent the recoil starter from operating properly.
- Bent or broken spring: A weak or broken spring can cause the recoil starter to spin slowly or not at all.
If you find any signs of damage or wear, you may need to replace the entire recoil starter assembly, not just the pull cord.
Steps to Replace Your Briggs & Stratton Lawn Mower Pull Cord
Step 1: Disengage the Spark Plug
Before you begin any work on the mower, safety is paramount. Disengage the spark plug by removing it from the spark plug wire. This will prevent the engine from starting accidentally.
Step 2: Remove the Recoil Starter Assembly Cover
The cover is typically held in place by screws or clips. Remove the screws or clips using your screwdriver and set them aside. Carefully remove the cover, being cautious as you may need to pry it off gently.
Step 3: Release the Old Pull Cord
The old pull cord is attached to the recoil starter assembly. Locate the end of the old pull cord and use your wire cutters to cut it as close to the assembly as possible. You may need to use your flathead screwdriver to pry it free if it’s stuck.
Step 4: Remove the Old Pull Cord from the Starter
Once you’ve cut the old pull cord, look for the small plastic piece where the cord is attached. This piece is typically held in place by a small screw. Carefully remove the screw, and the old pull cord will slide out.
Step 5: Install the New Pull Cord
Thread the new pull cord through the hole in the recoil starter assembly, making sure the end with the loop goes through first. It’s essential to keep the pull cord tension consistent, so ensure it sits flat and straight inside the mechanism.
Step 6: Reattach the Pull Cord to the Starter
Secure the new pull cord to the small plastic piece by re-inserting the screw you removed earlier. Make sure the screw is securely tightened.
Step 7: Reinstall the Recoil Starter Cover
After reattaching the new pull cord, carefully place the recoil starter cover back on the assembly. Ensure it sits flush with the housing, then reattach the screws or clips you removed earlier.
Step 8: Reconnect the Spark Plug Wire
You’ve successfully replaced the pull cord! Reconnect the spark plug wire to the spark plug, making sure it is securely fastened.
Step 9: Test the New Pull Cord
Now, you’re ready to test the new pull cord. Pull the cord firmly a few times. You should hear the recoil starter engage and the engine should turn over. If it doesn’t start, try adjusting the choke or checking for other potential issues.
Step 10: Lubricate the Recoil Starter (Optional)
For smoother operation, you can apply a small amount of WD-40 or a similar lubricant to the recoil starter mechanism.
Troubleshooting Common Issues
Even after replacing the pull cord, you might encounter some issues. Here are a few common problems and solutions:
The Engine Doesn’t Turn Over
Possible cause: The recoil starter mechanism is not working properly.
Solution: Inspect the recoil starter assembly for damaged parts, such as a broken spring or worn-out gears. If necessary, replace the entire assembly.
The Engine Starts But Dies Quickly
Possible cause: The carburetor is dirty or clogged, or there’s a fuel problem.
Solution: Clean or replace the carburetor, check the fuel lines for blockage, and make sure the fuel tank is full.
The Engine Starts But Runs Roughly
Possible cause: The spark plug is fouled or the engine is not getting enough air.
Solution: Replace the spark plug and make sure the air filter is clean.
The Pull Cord is Loose
Possible cause: The pull cord is not secured properly, or the recoil starter spring is weak.
Solution: Tighten the screws securing the pull cord, or replace the spring if it is worn out.
The Pull Cord Is Difficult to Pull
Possible cause: The recoil starter mechanism is stuck or the spring is too strong.
Solution: Apply lubricant to the mechanism, or adjust the spring tension.
Tips for Maintaining Your Lawn Mower
Regular maintenance is crucial for keeping your lawnmower in top shape. Here are a few tips:
- Change the oil regularly: This helps keep the engine clean and running smoothly.
- Clean the air filter: A dirty air filter restricts airflow and can cause engine problems.
- Inspect the spark plug: Make sure the spark plug is clean and has the correct gap.
- Check the fuel lines for leaks: Leaking fuel can be a fire hazard.
- Keep the blade sharp: A sharp blade cuts cleanly and prevents scalping.
Conclusion
Replacing your Briggs & Stratton lawnmower pull cord is a relatively simple process that anyone can do with the right tools and instructions. By following the steps outlined in this guide, you’ll be able to get your lawnmower back up and running in no time. Remember to prioritize safety by disconnecting the spark plug before starting any work. And don’t forget about regular maintenance – it will help your lawnmower last longer and perform better.
Frequently Asked Questions
How do I know if my lawn mower pull cord is broken?
The most obvious sign of a broken pull cord is that it won’t start your lawn mower. You might also notice the cord is frayed, snapped, or missing entirely. If you pull the cord and it feels loose, it’s likely broken or about to break.
If you experience any of these symptoms, it’s best to replace the pull cord immediately to avoid further damage to your lawn mower.
What tools will I need to replace my pull cord?
To replace your Briggs & Stratton lawn mower pull cord, you will need a few basic tools. These include a screwdriver (to remove the recoil housing), a pair of pliers (for gripping the old pull cord and the new one), and a wire cutter or scissors (for trimming the excess pull cord). If you have a new recoil spring, you’ll also need a spring compressor.
Having the right tools will make the process smoother and ensure you have everything you need on hand.
How long does it take to replace a lawn mower pull cord?
Replacing a lawn mower pull cord is a relatively quick and easy process, typically taking 15-30 minutes. This time frame includes removing the old cord, installing the new cord, and reassembling the recoil housing. However, the time can vary depending on the complexity of your specific lawn mower model.
If you’re comfortable working with tools and following instructions, replacing the pull cord is a DIY project that can save you money and time compared to hiring a professional.
Can I reuse the old pull cord housing?
