To keep your Husqvarna chainsaw up and running, you may have to replace different parts every now and then. One of the common components that require replacement in a chainsaw is a spark plug.
The spark plug model depends on the chainsaw model you have and the brand you’re getting the spark plug from. The best way is to check the user manual to see what spark plug is compatible with that particular model.
Let’s take a look at some chainsaw models and their compatible spark plugs first.
Spark Plug For Husqvarna Chainsaw
Different models from the same brand can use different spark plugs. The thing you should watch out for is the spark plug gap and the spark plug model.
The model of the spark plug will be different, depending on the brand you go for. For instance, you can get a spark plug from champion or NGK. Model numbers will be different for each of them.
The best way to make sure that you are not using the wrong spark plug is to check the user manual. This way, you can be certain the spark plug you are using matches the chainsaw. Using the wrong size or model can do damage to the engine.
This goes for any replacement components. When the replacement isn’t a proper fit, it can cause damage even when it’s working.
So, it’s always a good idea to take your time and look at the measurement needed to match the component to the chainsaw.
If you have a Stihl chainsaw, I also have an article on Stihl chainsaw spark plugs. Don’t forget to check it out before replacing the spark plug.

Signs Of A Faulty Spark Plug
If you want to keep your chainsaw on top of its potential, keeping the spark plug in check is mandatory. The spark plug ensures that the engine starts without struggling.
With time, the component can get damaged and struggle to provide the expected performance for your chainsaw. So, let’s take a look at the signs that could mean that you have a faulty spark plug:
- The chainsaw struggles to turn on.
- The engine runs roughly or often misfires.
- Your chainsaw stalls shortly after starting.
- You notice a significant increase in fuel consumption.
- The spark plug has visible damage like corrosion or carbon buildup.
How To Check Your Spark Plug
The first sign to look for in your spark plug is visible damage. Remove the spark plug from the chainsaw and look for rust or carbon building. Refer to the user manual to check how to remove the spark plug from a particular chainsaw.
If there is no visible damage, you will have to use an ignition tester to see if the spark plug is working. The ignition tester connects to the spark plug and the boot to allow the user to see whether the spark plug is still producing sparks.
How To Replace A Spark Plug On A Husqvarna Chainsaw
Replacing a spark plug is not a difficult task to do. Place the chainsaw on a flat surface and set the chain brake by pushing it forward. Remove the screws on the cover and remove the cover.
You will have to locate where the spark plug is. You can check your chainsaw’s user manual to do that. Once you find the spark plug, remove the boot. It’s a rubber part that covers the spark plug.
One end of the spark plug will be exposed once you remove the boot. Now, take your socket wrench and turn the spark plug anticlockwise until it gets loose. Remove the spark plug and place the new spark plug in the cylinder head.
Use the socket wrench again to tighten the spark plug. This time, use a clockwise motion. Make sure not to tighten it too much. Place the cover and screw it in place. Make sure to check whether the spark plug is working by using the chainsaw after replacement.

Safety Measures
Using a chainsaw is always a dangerous thing to do. Brands like Husqvarna produce commercial chainsaws, which means you have to be extra careful while operating one of them.
Let’s take a look at the safety measures you should keep in mind while using a chainsaw:
- The work environment is important. Always make sure that you are working in a well-ventilated area. If you are working indoors, keep all the doors and windows open to ensure sufficient ventilation.
- Watch out for fuel leakage before running the chainsaw.
- To protect your ears, always use earmuffs when running a chainsaw.
- If your chainsaw is behaving in a way it’s not supposed to, look out for damaged components.
- Always follow the manufacturer’s instructions. Different chainsaws may come with specialized safety instructions. Go through them before using the tool.
- Each chainsaw is different. So, even if you have used a chainsaw before, familiarize yourself with the new one before getting started.
