Your chainsaw won’t stay running because of a few possible reasons.
The carburetor is dirty. This is the most common cause of a chainsaw that won’t stay running. The carburetor mixes fuel and air to create the proper mixture for combustion. If the carburetor is dirty, it can’t mix the fuel and air properly, which will cause the chainsaw to run poorly or not at all.
The spark plug is fouled. The spark plug creates the spark that ignites the fuel/air mixture in the cylinder. If the spark plug is fouled, it won’t be able to create a spark, which will prevent the chainsaw from running.
The fuel filter is clogged. The fuel filter prevents dirt and debris from getting into the carburetor. If the fuel filter is clogged, it will restrict the flow of fuel to the carburetor, which will cause the chainsaw to run poorly or not at all.
To fix a chainsaw that won’t stay running, you’ll need to identify the cause of the problem and then fix it.
Why Won’T My Chainsaw Stay Running
There are a few reasons why your chainsaw might not be staying running.
Low oil level:
Make sure the oil level is correct. If the oil level is too low, the chainsaw will not be able to lubricate itself properly and will eventually overheat and stop running.
Clogged air filter:
A clogged air filter will restrict the flow of air to the engine, causing it to run lean and eventually stall. Clean or replace the air filter as needed.
Dirty spark plug:
A dirty spark plug will not be able to generate a spark strong enough to ignite the fuel, causing the chainsaw to misfire and eventually stall. Clean or replace the spark plug as needed.
Bad fuel:
Using old or stale fuel can cause the chainsaw to run poorly and eventually stall. Make sure to use fresh fuel that is free of contaminants.
Incorrect carburetor adjustment:
The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is not adjusted properly, the chainsaw will run lean or rich and eventually stall. Have the carburetor adjusted by a qualified technician.

Spark plug problems:
A dirty or fouled spark plug can prevent the engine from starting or running properly. Check the spark plug and clean or replace it if necessary.
Carburetor problems:
The carburetor is responsible for mixing the fuel and air in the correct proportions for the engine. If the carburetor is dirty or out of adjustment, it can cause problems with the engine’s performance.
Engine problems:
A chainsaw engine can develop a number of problems that can prevent it from running properly. These problems can include worn or damaged pistons, valves, or rings.
Troubleshooting Tips
If your chainsaw won’t stay running, here are some troubleshooting tips that you can try:
Check the fuel level:
Make sure that the chainsaw has enough fuel in the tank. If the fuel level is low, fill up the tank with fresh fuel.
Clean the spark plug:
Remove the spark plug from the chainsaw and clean it with a spark plug cleaner. If the spark plug is fouled, replace it with a new one.
Adjust the carburetor:
If the carburetor is dirty or out of adjustment, it can cause problems with the engine’s performance. Clean the carburetor and adjust the idle speed and fuel mixture according to the manufacturer’s instructions.
Inspect the engine:
If the chainsaw still won’t stay running, you may need to have the engine inspected by a qualified technician. The engine may have worn or damaged pistons, valves, or rings.
Preventative Maintenance
The best way to avoid problems with your chainsaw is to perform regular preventative maintenance. This includes:
Keeping the chainsaw clean:
Clean the chainsaw after each use to remove dirt, dust, and debris.
Lubricating the chain:
Lubricate the chain regularly to prevent it from becoming dry and gummy.
Adjusting the chain tension:
Keep the chain tension adjusted properly to prevent it from jumping off the bar.
Inspecting the engine:
Inspect the engine regularly for signs of wear and tear. Replace worn or damaged parts as needed.
By following these tips, you can help to ensure that your chainsaw stays running smoothly and efficiently.
