Why Chainsaw Won’T Stay Running
There are a few reasons why a chainsaw might not stay running.
Low oil level:
If the oil level is too low, the chainsaw will not be able to lubricate the engine properly and will eventually overheat and stop running.
Dirty air filter:
A dirty air filter will restrict the flow of air to the engine, causing it to run lean and eventually stall.
Clogged spark plug:
A clogged spark plug will prevent the engine from firing, causing it to stall.
Bad fuel:
Using old or bad fuel can cause the engine to run rough and eventually stall.
Misadjusted carburetor:
The carburetor is responsible for mixing the air and fuel in the correct proportions. If the carburetor is misadjusted, the engine will run lean or rich and eventually stall.

Chainsaw Won’t Start
There are a few reasons why your chainsaw might not start. Here are some of the most common causes and solutions:
Fuel problem:
Make sure that you have enough fuel in the tank and that the fuel is fresh. If the fuel is old, it can gum up the carburetor and prevent the chainsaw from starting.
Spark plug problem:
If the spark plug is fouled or damaged, it can’t produce a spark, which is necessary to start the chainsaw. Check the spark plug and replace it if necessary.
Cylinder compression problem:
If the cylinder is low on compression, it will be difficult to start the chainsaw. This can be caused by a number of problems, such as a worn piston or rings, a cracked cylinder head, or a leaking valve.
Carburetor problem:
The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is dirty or adjusted incorrectly, it can cause the chainsaw to run poorly or not start at all.

FAQs: Why Chainsaw Won’t Stay Running
Why won’t my chainsaw start?
The engine is flooded: If the engine is flooded, it means that too much fuel has been introduced into the cylinder. This can happen if you try to start the chainsaw too soon after it has been shut off, or if you choke the engine too much. To fix this problem, turn the chainsaw off and wait a few minutes for the excess fuel to evaporate. Then, try starting the chainsaw again.
The spark plug is fouled: A fouled spark plug can prevent the engine from starting. To check the spark plug, remove it from the engine and look at the electrodes. If they are covered in black carbon, the spark plug is fouled and needs to be replaced.
The air filter is dirty: A dirty air filter can restrict the flow of air to the engine, which can make it difficult to start. To check the air filter, remove it from the chainsaw and look at it. If it is dirty, replace it with a new one.
The carburetor is out of adjustment: The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is out of adjustment, it can cause the engine to run poorly or not start at all. To adjust the carburetor, you will need to consult your chainsaw’s owner’s manual.
The engine is overheating: If the engine is overheating, it can cause the spark plug to foul and the valves to stick. To prevent the engine from overheating, make sure that the air intake and exhaust ports are clear of debris. Also, avoid running the chainsaw at full throttle for extended periods of time.
What should I do if my chainsaw won’t start?
Check the spark plug: Remove the spark plug and look at the electrodes. If they are covered in black carbon, the spark plug is fouled and needs to be replaced.
Check the air filter: Remove the air filter and look at it. If it is dirty, replace it with a new one.
Adjust the carburetor: If the carburetor is out of adjustment, it can cause the engine to run poorly or not start at all. To adjust the carburetor, you will need to consult your chainsaw’s owner’s manual.
Check for obstructions in the air intake and exhaust ports: If the air intake or exhaust ports are blocked, it can prevent the engine from getting enough air or expelling exhaust gases. To clear the obstructions, use a small brush or wire to clean out the ports.
Let the engine cool down: If the engine is overheating, it can cause the spark plug to foul and the valves to stick. To prevent the engine from overheating, make sure that the air intake and exhaust ports are clear of debris. Also, avoid running the chainsaw at full throttle for extended periods of time.
How can I prevent my chainsaw from stalling?
Keep the chain sharp: A sharp chain will cut through wood more easily and will not require as much power from the engine.
Use the correct chain oil: The type of chain oil you use can make a big difference in how well your chainsaw runs. Use a chain oil that is specifically designed for chainsaws and that is compatible with the type of chain you are using.
Adjust the carburetor: The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is out of adjustment, it can cause the engine to run poorly or stall. To adjust the carburetor, you will need to consult your chainsaw’s owner’s manual.
Don’t overload the chainsaw: Trying to cut through wood that is too thick or too hard can cause the engine to stall. If you are having trouble cutting through a piece of wood, try using a smaller chain or slowing down the chainsaw.
