Your chainsaw won’t stay running because the carburetor is dirty.
A dirty carburetor can cause a number of problems, including
The chainsaw won’t start
The chainsaw starts but dies after a few seconds
The chainsaw runs but doesn’t have enough power
If you’re having trouble with your chainsaw, cleaning the carburetor is a good place to start. It’s a relatively simple process that can be done in a few minutes with a few basic tools.
Why My Chainsaw Won’T Stay Running
There are a few reasons why your chainsaw might not stay running.
Clogged air filter:
A clogged air filter can restrict the flow of air to the engine, causing it to run lean and eventually stall.
Dirty carburetor:
A dirty carburetor can cause the engine to run rich and eventually flood, causing it to stall.
Bad spark plug:
A bad spark plug can cause the engine to misfire and eventually stall.
Low oil level:
A low oil level can cause the engine to overheat and eventually stall.
Engine damage:
If the engine is damaged, it may not be able to run properly.
Why My Chainsaw Won’t Stay Running
There are a few reasons why your chainsaw might not be staying running. Here are some of the most common causes and how to fix them:
The carburetor is dirty:
If the carburetor is dirty, it can cause the chainsaw to run erratically or not at all. To clean the carburetor, you will need to remove it from the chainsaw and take it apart. Use a carburetor cleaner to clean all of the parts, and then reassemble the carburetor.
The spark plug is fouled:
A fouled spark plug can also cause a chainsaw to not stay running. To check the spark plug, remove it from the chainsaw and look at the electrode. If the electrode is black and sooty, the spark plug is fouled and needs to be replaced.
The air filter is dirty:
A dirty air filter can restrict airflow to the carburetor, which can cause the chainsaw to run poorly or not at all. To clean the air filter, remove it from the chainsaw and shake it out. If the air filter is very dirty, you can also rinse it with water and let it dry completely before reinstalling it.
The fuel filter is clogged:
A clogged fuel filter can prevent fuel from reaching the carburetor, which can cause the chainsaw to run poorly or not at all. To check the fuel filter, remove it from the chainsaw and look at it. If the filter is clogged, replace it with a new one.
The chainsaw is out of fuel:
If the chainsaw is out of fuel, it will not run. Make sure that the chainsaw is filled with fuel before trying to start it.
The chainsaw is not getting spark:
If the chainsaw is not getting spark, it will not run. To check for spark, remove the spark plug from the chainsaw and hold it against the engine block. Crank the engine over and look for a spark at the spark plug. If there is no spark, check the spark plug wire and make sure that it is connected to the spark plug properly. If the spark plug wire is connected properly, replace the spark plug.
If you have tried all of these things and your chainsaw still won’t stay running, you may need to take it to a qualified chainsaw repair technician.
Preventative Maintenance
In addition to fixing the problems that can cause a chainsaw to not stay running, you can also take steps to prevent these problems from happening in the first place. Here are a few tips for preventative maintenance:
Clean the carburetor regularly:
A dirty carburetor can cause a chainsaw to run erratically or not at all. To prevent this, clean the carburetor at least once a year.
Replace the spark plug regularly:
A fouled spark plug can also cause a chainsaw to not stay running. To prevent this, replace the spark plug at least once a year.
Clean the air filter regularly:
A dirty air filter can restrict airflow to the carburetor, which can cause the chainsaw to run poorly or not at all. To prevent this, clean the air filter at least once a month.
Replace the fuel filter regularly:
A clogged fuel filter can prevent fuel from reaching the carburetor, which can cause the chainsaw to run poorly or not at all. To prevent this, replace the fuel filter at least once a year.
Store the chainsaw properly:
When you are not using the chainsaw, store it in a cool, dry place. This will help to prevent the carburetor from becoming dirty and the spark plug from becoming fouled.
By following these tips, you can help to keep your chainsaw running smoothly and prevent problems from occurring.
