Replacing the Pull Cord on Your Stihl Blower: 5 Pro Tips for a Smooth Start
Here’s how I tackle this common issue, turning a potential headache into a quick, efficient repair.
1. Diagnosing the Problem: Is it Really the Cord?
First things first, before you start tearing things apart, let’s confirm that the pull cord is indeed the culprit. Sometimes, a hard-to-start blower points to other issues like a clogged carburetor or a faulty spark plug.
How to Check:
- Visual Inspection: Examine the cord for fraying, breaks, or excessive wear. A visibly damaged cord is a clear indicator.
- Pull Test: Gently pull the cord. Does it retract smoothly? If it’s stuck, loose, or doesn’t retract, the cord or the recoil mechanism is likely the issue.
- Listen Carefully: When you pull the cord, listen for unusual noises like grinding or scraping. These sounds might indicate a problem with the recoil spring or other internal components.
I recall one time I was convinced it was the pull cord. I spent almost an hour taking it apart and replacing it, only to find out that the spark plug was the real problem. Now, I always start with the simplest checks first.
2. Gathering Your Tools and Materials: The Right Gear for the Job
Having the right tools makes all the difference. It’s like trying to carve a turkey with a butter knife – possible, but frustrating.
Essential Tools:
- New Pull Cord: Use the correct diameter and length for your specific Stihl blower model. Check your owner’s manual for this information. I prefer a high-quality nylon or polyester cord for durability.

Data Point: Using the wrong diameter cord can cause it to bind or slip, leading to premature wear or failure. Always consult your blower’s manual for the correct specifications.
Personal Story: I once tried to save a few bucks by using a cheaper, thinner cord. It snapped after only a few uses. Lesson learned: invest in quality.
3. The Disassembly Process: Patience is Key
This is where things can get tricky, but with a little patience, it’s manageable.
Step-by-Step Guide:
- Remove the Starter Housing: Locate the screws holding the starter housing to the blower. Remove them and carefully detach the housing.
- Secure the Recoil Mechanism: Before removing the cord, you need to secure the recoil mechanism to prevent it from unwinding violently. Some models have a locking mechanism; others require you to hold the pulley in place.
- Remove the Old Cord: Locate the knot or fastener at the pulley end of the cord. Untie or detach it. Then, carefully pull the cord out of the handle.
- Inspect the Recoil Spring: While the housing is open, inspect the recoil spring for damage or wear. If it’s broken or weak, now is the time to replace it.
Unique Insight: Take pictures as you disassemble the housing. This will be invaluable when you reassemble it, especially if you’re new to this.
Common Mistake: Letting the recoil spring unwind completely. This can be dangerous and difficult to fix. Always secure the mechanism before removing the cord.
4. Installing the New Cord: The Art of Threading
Threading the new cord can be a bit fiddly, but here’s how I make it easier.
Step-by-Step Guide:
- Thread Through the Handle: Use a small punch or awl to help guide the new cord through the handle.
- Thread Through the Housing: Carefully thread the cord through the hole in the starter housing and into the pulley.
- Secure the Cord to the Pulley: Tie a secure knot at the end of the cord, or use the fastener provided. Make sure the knot is tight and won’t slip.
- Pre-Tension the Recoil Spring: This is crucial for smooth retraction. Rotate the pulley in the direction it needs to wind (usually clockwise) several times to pre-tension the spring. Refer to your blower’s manual for the exact number of rotations.
- Secure the Recoil Mechanism: While holding the pulley in place, carefully release the locking mechanism (if applicable) or maintain tension on the pulley.
Practical Tip: Use a pair of needle-nose pliers to help you grip and manipulate the cord, especially when tying the knot.
Data Point: Pre-tensioning the recoil spring incorrectly can result in a cord that either doesn’t retract fully or retracts too forcefully, leading to premature wear.
5. Reassembly and Testing: The Moment of Truth
Putting everything back together and testing your work is the final step.
Step-by-Step Guide:
- Reassemble the Starter Housing: Carefully align the starter housing with the blower and reattach it using the screws you removed earlier.
- Test the Cord: Pull the cord several times to ensure it retracts smoothly and completely. Listen for any unusual noises.
- Start the Blower: Now for the real test. Start the blower and see if it runs smoothly.
Troubleshooting:
- Cord Doesn’t Retract: You may not have pre-tensioned the recoil spring enough. Disassemble the housing and add a few more rotations.
- Cord is Difficult to Pull: The cord may be binding. Check for obstructions or misalignments in the housing.
- Blower Still Doesn’t Start: The problem may be something else entirely, such as a clogged carburetor or a faulty spark plug.
Personal Story: I once spent hours troubleshooting a blower that wouldn’t start after replacing the pull cord. Turns out, I had accidentally dislodged the spark plug wire during the process. Always double-check the basics.
