When it comes to maintaining your Stihl chainsaw, one of the most crucial components to check and replace is the spark plug wire. A faulty spark plug wire can lead to poor engine performance, reduced power output, and even complete engine failure. Replacing the spark plug wire on your Stihl chainsaw is a relatively simple process that can be done at home with the right tools and knowledge. In this article, we will guide you through the process of replacing the spark plug wire on your Stihl chainsaw, and provide you with the necessary information to get the job done correctly.
Why Replace the Spark Plug Wire?
The spark plug wire is responsible for transmitting the high voltage from the ignition coil to the spark plug, which ignites the fuel-air mixture in the engine. Over time, the spark plug wire can become worn out, damaged, or corroded, leading to poor engine performance and reduced power output. Replacing the spark plug wire can help to restore your Stihl chainsaw’s performance and ensure that it runs smoothly and efficiently.
Tools and Materials Needed
To replace the spark plug wire on your Stihl chainsaw, you will need the following tools and materials:
- A spark plug wire puller
- A new spark plug wire
- A spark plug gap gauge
- A screwdriver or wrench
- A pair of gloves
Step-by-Step Instructions
Removing the Old Spark Plug Wire
To remove the old spark plug wire, you will need to use a spark plug wire puller. This tool is designed specifically for removing spark plug wires and is available at most hardware stores or online.
Step 1: Locate the spark plug wire on your Stihl chainsaw. It is usually located on the side of the engine or on the spark plug itself. Step 2: Use the spark plug wire puller to grip the spark plug wire and pull it off the spark plug. Step 3: Once the spark plug wire is removed, use a screwdriver or wrench to loosen any retaining clips or screws that may be holding it in place. Step 4: Carefully pull the spark plug wire off the spark plug and set it aside.
Installing the New Spark Plug Wire
To install the new spark plug wire, you will need to follow the same steps as removing the old one. However, you will need to make sure that the new spark plug wire is properly seated on the spark plug and that any retaining clips or screws are securely tightened.

Step 1: Take the new spark plug wire and insert the end that goes into the spark plug into the spark plug. Step 2: Use the spark plug wire puller to pull the spark plug wire onto the spark plug, making sure that it is properly seated. Step 3: Use a screwdriver or wrench to tighten any retaining clips or screws that may be holding the spark plug wire in place. Step 4: Double-check that the spark plug wire is properly seated and that any retaining clips or screws are securely tightened.
Checking the Spark Plug Gap
Once the new spark plug wire is installed, it is important to check the spark plug gap to ensure that it is set correctly. The spark plug gap is the distance between the center electrode and the ground electrode on the spark plug. If the spark plug gap is set too wide or too narrow, it can cause poor engine performance and reduced power output.
Step 1: Use a spark plug gap gauge to measure the distance between the center electrode and the ground electrode on the spark plug. Step 2: Compare the measured distance to the recommended spark plug gap for your Stihl chainsaw, which can be found in the owner's manual or on the manufacturer's website. Step 3: If the measured distance is not within the recommended range, adjust the spark plug gap by bending the center electrode or the ground electrode to the correct distance.
Conclusion
Replacing the spark plug wire on your Stihl chainsaw is a relatively simple process that can be done at home with the right tools and knowledge. By following the steps outlined in this article, you can ensure that your Stihl chainsaw runs smoothly and efficiently. Remember to always follow the recommended maintenance schedule for your Stihl chainsaw and to consult the owner’s manual if you have any questions or concerns.
