If you’re familiar with the Husqvarna chainsaw, you know how efficient this machine can be. However, the chainsaw might develop problems over time; for instance, the chainsaw choke may fail to stay up. So, what could cause this problem, and how can you fix it?
A defective spark plug, carburetor, and a clogged air filter can cause the Husqvarna chainsaw choke to malfunction. You should try adjusting the carburetor or cleaning the air filter to fix the problem. If that doesn’t work, you can replace the chainsaw altogether.
In this article, I’ll discuss possible reasons why your Husqvarna Chainsaw choke won’t stay up. I’ll also discuss ways to fix these issues. So read on to learn more.
Why Husqvarna Chainsaw Choke May Fail To Stay Up
If you’re a Husqvarna chainsaw user, you know that a properly functioning choke is essential to operate the saw. However, it might just be those unlucky days when you realize that your chainsaw can’t stay up. It’s frustrating, but don’t despair.
Here are a few reasons why you’re experiencing this problem:
1. The Chainsaw Isn’t Getting Enough Air
A chainsaw needs enough air to operate. So, if your chainsaw isn’t getting enough air, it will fail to stay up.
One of the main reasons a chainsaw won’t get enough air is that the engine isn’t properly tuned. When the engine isn’t tuned, it doesn’t produce enough power to turn the chain and move the saw through the wood.
Another reason for the airflow problem might be that the saw’s chain is too tight. The chain must be tight enough to cut through the wood (source). However, if it’s too tight, it can restrict airflow and cause the engine to overheat.
How To Fix
One of the most important things you can do to ensure your chainsaw runs properly is to remove any debris blocking the airflow.
Check the air intake regularly and clear away any unwanted materials. This will help keep your chainsaw running smoothly and prevent any potential problems.
2. The Air Filter Is Dirty or Clogged
The air filter is an essential component of a chainsaw (source). It helps enhance the performance and lifespan of your saw.
Ideally, the air filter keeps the engine clean by trapping dirt and debris. However, if it’s too dirty, it can restrict airflow and cause your chainsaw to stop running.
How To Fix
Cleaning the saw’s air filter can help to prevent some common malfunctions of the tool. I would recommend cleaning the air filter regularly, after every 12 tanks of fuel or 6 hours of use.
It’s also important to replace your filter regularly. If possible, replace it every 12 months.
3. A Defective Spark Plug
The spark plug creates the electrical current that ignites the fuel. If your chainsaw’s spark plug isn’t working properly, it won’t be able to harness enough electricity to ignite the fuel. As a result, it will be impossible for your chainsaw to keep running.
How To Fix
There are a few things you can do to fix a defective spark plug:
- First, ensure the spark plug is clean and free of debris. If it’s dirty, you’ll need to clean it.
- Next, check the gap between the electrode and the ground. If it’s too wide, you’ll need to adjust it.
- Finally, if all else fails, you may need to replace the spark plug altogether.
4. The Carburetor Is the Problem
A carburetor mixes fuel and air, which starts the internal combustion engine.
If your chainsaw’s carburetor is faulty, it can make the chainsaw choke to stop running. This problem is usually caused by a build-up of dirt and debris in the carburetor.
How To Fix
Adjusting the carburetor is a relatively easy fix. You can do this at home with only a few tools.
To adjust the carburetor, you’ll need to:
- Locate the carburetor adjustment screws on the side of the carburetor.
- Use a screwdriver to turn the screws until the choke plate is in the correct position.
- Once the choke plate is in the correct position, tighten the screws to secure it.
Sometimes, a simple carburetor adjustment may fail to solve the problem. If this is the case, you can proceed to check for any damages or if the carburetor is clogged.
If the carburetor is clogged, you’ll have to clean it (source). This will require draining any fuel in the saw. Then, use a clean chainsaw carburetor solution to spray the carburetor. RC Carb & Choke Cleaner (link to Amazon) can do the cleaning well. It acts quickly to clean the carburetor and you can even buy it in bulk to save money.
Ensure you wipe the carburetor after cleaning before starting your saw.
5. Poor Fuel Quality in the Tank
The problem can also result from poor-quality fuel. Fuel quality in your chainsaw affects how well the saw will run.
Fuel left for long in the saw can also make the carburetor stinky and messy.
If the fuel is of poor quality, the saw may not start at all, or it may run erratically. This can be dangerous, as a chainsaw is a powerful tool that can cause injury if you don’t use it properly.
How To Fix
It’s critical to assess the type and state of fuel in the saw. If you want your chainsaw to run smoothly and efficiently, you’ll need to use good-quality fuel.
In the case of old fuel in the tank, it’s important to drain the gas tank, clean it, then refill it with fresh fuel. It’s worth spending a little extra on good fuel to keep your chainsaw in top condition.
6. The Chainsaw Is Worn Out
A chainsaw can be a very useful tool, but it won’t perform well if worn out. Gradual wear and tear of the saw can make the blade dull. Likewise, this can cause the chain not to move as quickly or smoothly.
If you’re using a relatively older chainsaw, it’s time you consider possible wear and tear.
How To Fix
At this point, it may be advisable to talk to a professional. You can contact the Husqvarna support team for further assistance. They’ll be able to diagnose the saw further and tell you what’s wrong with it.
With a little troubleshooting, you may be able to get your chainsaw running properly again.
If the Husqvarna support team can’t fix the problem, you’ll have to replace it entirely. Luckily, replacing a chainsaw is relatively easy.
Husqvarna makes great saws, so you can be sure to find a good replacement. A new chainsaw will help you get the job done quickly and efficiently.

Final Remarks
A Husqvarna chainsaw is a handy tool. However, the chainsaw choke may fail to stay up. This can be due to a dirty air filter, defective spark plug, and carburetor problems.
Fortunately, there are several things you can do to fix the problem. For instance, you can clean the air filter if it’s dirty. You can also check and fix any spark plug and carburetor errors. Additionally, you can replace the fuel in the tank if it’s no longer efficient.
If the problem persists, talk to a professional or replace the saw.
