Your Chainsaw Won’t Start Here’s Why
There are a few reasons why your chainsaw might not start. It could be a problem with the spark plug, the carburetor, or the air filter. In this blog post, we’ll take a look at each of these potential causes and how to fix them. We’ll also provide some tips on how to prevent your chainsaw from starting in the future.
Why Won’T Chainsaw Start
Chain saws won’t start for a variety of reasons, including:
Fuel:
Make sure the chainsaw has fuel and that the fuel is fresh.
Spark:
Check the spark plug and make sure it is in good condition and has a spark.
Cylinder:
Check the cylinder and make sure it is clean and free of obstructions.
Carburetor:
Clean the carburetor if it is dirty.
Engine:
If the engine is seized, it will need to be repaired or replaced.
Why Won’t My Chainsaw Start?
There are a few reasons why your chainsaw might not start.
The engine is not getting fuel:
This could be due to a number of problems, such as a clogged fuel filter, a faulty fuel pump, or a problem with the carburetor.
The engine is not getting spark:
This could be due to a bad spark plug, a faulty ignition coil, or a problem with the wiring.
The engine is flooded:
This can happen if you accidentally start the chainsaw while it is flooded with fuel. To fix this, turn the chainsaw off and let it sit for a few minutes. Then, try starting it again.
The engine is seized:
This can happen if the chainsaw is not used for a long period of time. To fix this, you will need to remove the spark plug and pour a few drops of oil into the cylinder. Then, turn the crankshaft over a few times with the starter rope. Finally, replace the spark plug and try starting the chainsaw again.
How to troubleshoot a chainsaw that won’t start
If your chainsaw won’t start, here are a few things you can check:
1. Check the fuel level:
Make sure that there is enough fuel in the tank. If the tank is empty, fill it up with fresh fuel.
2. Check the fuel filter:
Remove the fuel filter and inspect it for dirt or debris. If the filter is clogged, clean it or replace it.3. Check the fuel pump:
If the fuel pump is not working properly, it will not be able to deliver fuel to the engine. To test the fuel pump, remove the fuel line from the carburetor and turn the chainsaw on. If fuel does not come out of the fuel line, the fuel pump is faulty and will need to be replaced.
4. Check the carburetor:
The carburetor is responsible for mixing air and fuel in the correct proportions. If the carburetor is not adjusted properly, it will not be able to provide the engine with the correct mixture of air and fuel. To test the carburetor, you will need to remove it from the chainsaw and clean it. You can also adjust the carburetor’s settings, but this is a more advanced procedure and should only be attempted by experienced mechanics.
5. Check the spark plug:
The spark plug is responsible for providing the spark that ignites the fuel in the engine. If the spark plug is faulty, it will not be able to provide the engine with a spark. To test the spark plug, remove it from the engine and connect it to the spark plug wire. Then, ground the spark plug against the engine block and turn the chainsaw on. If you see a spark, the spark plug is working properly. If you do not see a spark, the spark plug is faulty and will need to be replaced.
6. Check the ignition coil:
The ignition coil is responsible for generating the high voltage spark that ignites the fuel in the engine. If the ignition coil is faulty, it will not be able to generate the spark. To test the ignition coil, you will need to remove it from the engine and connect it to a multimeter. Set the multimeter to the AC voltage setting and connect the leads to the ignition coil’s terminals. Turn the chainsaw on and check the multimeter. If you see a reading of 100-200 volts, the ignition coil is working properly. If you do not see a reading, the ignition coil is faulty and will need to be replaced.
7. Check the wiring:
The wiring between the spark plug, the ignition coil, and the starter switch can become damaged or corroded over time. This can prevent the spark plug from receiving a spark. To test the wiring, you will need to inspect it for damage or corrosion. If you find any damage, you will need to repair or replace the wiring.
8. Check the engine:
If the engine is seized, it will not be able to start. To check the engine, you will need to remove the spark plug and turn the crankshaft over with the starter rope. If the crankshaft does not turn freely, the engine is seized and will need to be repaired or replaced.
How to prevent your chainsaw from starting
To prevent your chainsaw from starting, you can take the following steps:
Make sure that the fuel tank is full:
A full fuel tank will help to prevent the fuel from evaporating and becoming stale.
Use fresh fuel:
Old fuel can become stale and will not burn properly.
Keep the fuel filter clean:
A clogged fuel filter can prevent the engine from getting enough fuel.

FAQs: Why Won’t My Chainsaw Start?
What are the most common reasons why a chainsaw won’t start?
The chainsaw is out of gas: This is the most common reason why a chainsaw won’t start. Make sure the chainsaw is filled with gas and that the gas cap is properly tightened.
The chainsaw is not getting spark: This can be caused by a faulty spark plug, a bad ignition coil, or a loose connection between the spark plug wire and the spark plug.
The chainsaw’s carburetor is dirty or clogged: This can prevent the chainsaw from getting the proper amount of fuel and air, which can cause it to stall or not start at all.
The chainsaw’s chain is too tight or too loose: A chain that is too tight can cause the chainsaw to stall, while a chain that is too loose can come off the sprocket and cause injury.
The chainsaw’s air filter is dirty: A dirty air filter can restrict airflow to the chainsaw’s engine, which can cause it to run poorly or not start at all.
How do I fix a chainsaw that won’t start?
1. Check the gas level: Make sure the chainsaw is filled with gas and that the gas cap is properly tightened.
2. Check the spark plug: Remove the spark plug and check to see if it is fouled or damaged. If the spark plug is fouled, clean it with a spark plug cleaner or replace it with a new one.
3. Check the ignition coil: Disconnect the spark plug wire from the spark plug and touch the end of the wire to the engine block. If you see a spark, the ignition coil is working properly. If you don’t see a spark, the ignition coil is faulty and needs to be replaced.
4. Clean the carburetor: If the chainsaw’s carburetor is dirty or clogged, it can prevent the chainsaw from getting the proper amount of fuel and air, which can cause it to stall or not start at all. To clean the carburetor, you will need to remove it from the chainsaw and follow the manufacturer’s instructions for cleaning it.
5. Adjust the chain tension: If the chainsaw’s chain is too tight or too loose, it can cause the chainsaw to stall or not start at all. To adjust the chain tension, you will need to loosen the chain tensioner bolt and then adjust the chain tension by turning the chain tensioner screw.
6. Clean the air filter: A dirty air filter can restrict airflow to the chainsaw’s engine, which can cause it to run poorly or not start at all. To clean the air filter, you will need to remove it from the chainsaw and rinse it with warm water. You can also use a mild detergent to clean the air filter, but be sure to rinse it thoroughly with warm water afterwards.
What should I do if I can’t fix my chainsaw?
If you can’t fix your chainsaw, you can take it to a qualified chainsaw repair shop. A qualified chainsaw repair shop will be able to diagnose the problem and fix it properly.
How can I prevent my chainsaw from not starting?
To prevent your chainsaw from not starting, you can:
Keep the chainsaw clean and well-maintained: This includes regularly cleaning the air filter, spark plug, and carburetor.
Store the chainsaw in a cool, dry place: Storing the chainsaw in a warm, humid environment can cause the carburetor to become gummed up and the spark plug to foul.
Use the correct type of fuel: Use a fuel that is designed for chainsaws and that is fresh. Old or stale fuel can cause the carburetor to become gummed up.
Don’t over-tighten the chain: Over-tightening the chain can cause the chain to come off the sprocket and cause injury.
Don’t run the chainsaw dry: Running the chainsaw dry can damage the engine.
