The familiar roar of your lawnmower suddenly replaced by a frustrating silence? That dreaded “clunk” instead of the satisfying “whirr”? You’ve likely encountered the dreaded pull starter problem. Don’t worry, it’s a common issue and usually an easy fix. This article will guide you through the most common pull starter problems, how to troubleshoot them, and provide step-by-step instructions for repair. We’ll cover everything from diagnosing the issue to replacing worn-out parts, equipping you with the knowledge to tackle this lawnmower challenge head-on.
A Quick Overview
The pull starter is the mechanism that allows you to crank your lawnmower engine. It typically consists of a rope, a recoil spring, a starter pawl, and a starter housing. When you pull the rope, the spring winds up, releasing energy to spin the engine crankshaft. Issues can arise in any of these components, leading to a broken pull starter. This article will break down the common symptoms of a broken pull starter and the solutions to resolve them.
Common Signs of a Broken Pull Starter
Identifying the problem is the first step to fixing your pull starter. Here are some telltale signs:
- The pull rope doesn’t retract: This is a clear indication that the recoil spring is broken or malfunctioning.
- The rope feels loose and floppy: This could be a sign of a worn or broken spring, a loose pawl, or even a problem with the starter housing itself.
- The engine doesn’t crank: A broken pawl, worn spring, or a jammed starter housing can prevent the engine from cranking.
- The pull rope snaps: This could be due to a faulty rope, a damaged housing, or even excessive force applied while pulling the rope.
- The pull rope feels very hard to pull: This could signify a jammed starter housing, a worn or broken spring, or a seized engine.
Troubleshooting Your Pull Starter
Before you dive into repairs, it’s essential to isolate the issue. Here are some basic troubleshooting steps:
1. Inspect the Pull Rope and Housing
- Examine the pull rope: Check for fraying, breaks, or excessive wear. A damaged rope needs replacement.
- Check the starter housing: Look for cracks, damage, or loose screws. Secure any loose components or replace a damaged housing.
2. Test the Recoil Spring
- Pull the rope: If the rope feels loose and doesn’t retract easily, the recoil spring might be broken.
- Release the rope slowly: As you release the rope, listen for any “clicking” or unusual noises. This could indicate a spring that’s not working properly.
3. Inspect the Starter Pawl
- Locate the pawl: It’s a small metal piece located inside the starter housing, responsible for engaging the crankshaft.
- Check for wear and tear: Look for damage, broken teeth, or any other signs of wear.
- Test for proper engagement: Pull the rope and observe if the pawl correctly engages the crankshaft.

Frequently Asked Questions
How do I know if my pull starter is broken?
The most obvious sign of a broken pull starter is that the engine won’t start when you pull the cord. You might hear a click or a grinding sound instead of the engine cranking. Other signs include a loose or broken recoil spring, a damaged starter rope, or a worn-out starter pawl.
If you notice any of these symptoms, it’s a good idea to inspect your pull starter and make sure all the parts are in good working order. If you’re not sure how to do this, you can always consult a repair manual or take your lawnmower to a qualified mechanic.
What tools do I need to fix a pull starter?
You will need a few basic tools to fix a pull starter on a lawnmower. These include a screwdriver, a wrench, and a pair of pliers. You may also need a new pull starter rope and a starter pawl. It’s a good idea to have a repair manual handy, as it will provide detailed instructions on how to disassemble and reassemble the pull starter.
If you don’t have all the necessary tools, you can always buy them at a local hardware store. Be sure to choose tools that are the right size for your lawnmower.
How do I remove the pull starter?
To remove the pull starter, first, you need to disconnect the spark plug wire to prevent accidental ignition. Then, you’ll need to remove the cover that protects the pull starter. This usually involves removing a few screws. Once the cover is off, you should be able to see the pull starter assembly. Locate the retaining nut that holds the starter assembly in place and use a wrench to loosen it.
Once the nut is loose, you can gently pull the starter assembly out of the housing. Be careful not to damage the starter rope or other parts of the assembly.
How do I replace the pull starter rope?
To replace the pull starter rope, you will need to remove the old rope from the starter assembly. This can be done by cutting the rope at the point where it is attached to the starter housing. Once the old rope is removed, you can thread the new rope through the starter assembly, following the same path as the old rope.
It’s important to make sure that the new rope is the correct length and that it is properly secured to the starter housing. You may need to adjust the tension of the rope by turning the adjustment nut on the starter assembly.
How do I replace the starter pawl?
The starter pawl is a small metal part that engages with the flywheel to start the engine. Over time, the starter pawl can become worn or damaged. If you find that your starter pawl is damaged, you’ll need to replace it.
To replace the starter pawl, you’ll need to remove the old pawl from the starter assembly. This can be done by using a small screwdriver or a pair of pliers. Once the old pawl is removed, you can install the new pawl in its place. Make sure that the new pawl is properly seated and that it engages with the flywheel.
How do I lubricate the pull starter?
Lubricating the pull starter can help prevent it from wearing out prematurely. You can lubricate the pull starter by applying a small amount of grease to the moving parts, such as the starter pawl, the starter rope, and the recoil spring.
Be sure to use a grease that is designed for use with lawnmower parts. Avoid using too much grease, as this can make the pull starter difficult to operate.
How do I test the pull starter?
After you’ve made repairs to your pull starter, it’s important to test it to make sure it’s working properly. Start by pulling the cord a few times to make sure it’s engaging with the flywheel. You should hear a clicking sound as the pawl engages and disengages.
If the pull starter feels stiff or doesn’t engage with the flywheel, you may need to adjust the tension of the recoil spring or replace the starter pawl. Once you’re satisfied with the performance of the pull starter, you can reconnect the spark plug wire and start the engine.
