B) Determine What Parts Need Replacement
1. First, you must identify whether the Recoil Spring is in good condition and working correctly. If the recoil spring appears damaged or has no tension to recoil back to its origination point, it’s highly recommended that you get rid of that one and buy a new spring and pulley assembly.
It’s much easier than repairing or replacing just that recoil spring. However, if you’re in a hurry and want to repair the coil spring at home, see our suggested video below.
2. If the Recoil Spring appears to have the correct action and returns to its coil efficiently, you probably need a new Pull Cord Rope, which is relatively inexpensive. Some are sold with the handle, some without, but the main thing is making sure the new pull cord is the same thickness as the one you’re replacing.
3. Purchasing the correct pull cord thickness is a critical step. Amazon sells the most common pull cord with a handle included here: Briggs & Stratton pull cord.
A pull cord that’s too thick won’t fit properly, and a thin one will work OK but will have a shorter life. For this fix, match up the pull cord you remove with the one you buy.
How to Replace Worn-Out Pull Cord on a Lawnmower
Step-By-Step Instructions to Replace Pull Cord
Is it Easy to replace a pull cord on a lawn mower? Well, it depends on your DIY skills, but for most homeowners, we consider this job a 7 on a 1-10 scale, with 10 being the hardest of DIY tasks.
- Now, it’s time to pull the cord out of its assembly, ensuring your thumb holds the pulley firmly. For this Step: Don’t let it retract, or you will have to start over.
By the way, the question of How much a pull cord costs for a lawn mower definitely shouldn’t scare you off – A new pull cord costs less than USD 10 to replace.
2. Using both hands, gently wind the pulley assembly counter-clockwise gradually until the tension tells you it’s fully wound. Keeping a firm grasp, slowly let the pulley release until the rope hole on the pulley lines up with the hole in the housing.
Then, Insert a screwdriver to hold the spool firmly in place.
3. Measure the new pull cord against the old one to ensure you have the correct length. Do not remove the old one just yet.
4. Remember the lighter method mentioned above? Now it’s time to use it! Melting the end of the cord slowly with a lighter makes it easier to fit through both holes in the housing and in the handle. You could also push it through using your screwdriver.
5. It’s now safe to cut the knot off the cord attached to the pulley assembly and remove it. Insert the new pull cord, and double knot it to ensure it’s well secured.
6. Holding the wound pulley firmly, remove the screwdriver to unlock the pulley.
Slowly release the pulley to allow the new pull rope to retract into the pulley, secure it with your hand, and STOP when you have 18” of cord left to retract and tie it into a temporary knot. This will hold tension on the recoil spring.
7. Tie a double knot at the end of the “pull cord handle.”
8. Remove the temporary knot from the 18” of extra cord, and slowly let the recoil spring retract the extra cord. Test the Pull Cord assembly with a light pull and hold the handle to allow the pulley to retract slowly.
9. Place the starter assembly back on the lawnmower, fasten it, and insert the Pull Rope and Handle back in place.
10. Test the pull cord assembly with fresh gasoline and a new spark plug – by starting the mower, and off you go!
Some quick and essential tips:
Temporarily remove the spark plug on your mower before working on it.
After removing the pull cord assembly from the lawnmower, test it by pulling out the cord to see if it retracts back properly when recoiling.
Test the pull cord assembly after repair, after fixing each part, and before you reinstall it on the mower.
The problem could be a damaged spring. In that case, you might need to remove the pulley from the assembly.
Although most pulleys don’t require removal, it may depend on the quality of your lawnmower. It’s recommended to buy a new spring with the starter pulley (one unit) and install it.
Always have a small box or container handy for the small parts needing removal to avoid losing them.

3) Pull Cord Works, But the Engine Won’t Start?
A: If your pull cord works but the lawn mower engine won’t start, you may have a clog in your fuel line or fuel filter. The other most likely problem is that you’re using old gasoline (last year’s gas) or have a bad spark plug.
Either of these issues is easy to remedy. Flush out the bad gas and replace it with a new spark plug. Both are inexpensive solutions. Remember, only two things are required to start a combustible engine: gas and spark.
Tip: Replace each of those two items together or one at a time, then try to start the mower again.
