Why Your Chainsaw Won’t Start Best Reasons 2022

Chainsaws are invaluable tools for anyone who needs to regularly clear their property of fallen trees, branches, or other debris. However, even the most reliable chainsaw can have issues starting from time to time. If your chainsaw won’t start, there are a few potential reasons why.

How To Check for Possible Problems If Your Chainsaw Won’t Start?

Before you start troubleshooting, it’s important to check for any possible problems that could be causing your chainsaw to have difficulty starting. Here are a few things to look for:

Check It Has Fuel

Check the fuel tank to see if there is enough fuel. If the tank is empty, add fresh fuel and try starting the chainsaw again.

Check It Has Fresh Fuel

The chainsaw has afresh fuel in it? Gasoline doesn’t last long, tendency to gum up if the fuel is old. If you’ve had the same can of fuel sitting around for a while, it might be time to get a new one.

If your chainsaw has old fuel, drain it and replace it with fresh fuel.

Is The Carburetor Clogged?

If your chainsaw is having trouble starting, one possible reason is that the carburetor is clogged. Over time, the carburetor can become gummed up with residue from the fuel, which can prevent it from working properly.

Is The Carburetor Clogged?

To clean the carburetor, you’ll need to remove it from the chainsaw. Once it’s removed, use a carburetor cleaning kit to clean all of the parts. Be sure to follow the instructions carefully so you don’t damage the carburetor.

Once the carburetor is clean, reassemble it and try starting the chainsaw again.

Check The Spark Plug

If the carburetor is clean and there is fresh fuel in the tank, the next thing to check is the spark plug. The spark plug is responsible for igniting the fuel, so if it’s not working properly, the chainsaw won’t start.

To check the spark plug, remove it from the chainsaw and inspect it. If the spark plug is dirty, clean it with a wire brush. If the spark plug is damaged, replace it with a new one.

Once you’ve checked or replaced the spark plug, try starting the chainsaw again.

Check The Engine Isn’t Flooded

Another possible reason why your chainsaw won’t start is that the engine is flooded. This can happen if you try to start the chainsaw when it’s already warm, or if you don’t let the chainsaw cool down properly after using it.

If you think the engine might be flooded, remove the spark plug and inspect it. If the spark plug is wet, the engine is likely flooded.

To fix a flooded engine, remove the spark plug and wait a few minutes for the engine to dry out. Once the engine is dry, replace the spark plug and try starting the chainsaw again.

If you’re still having trouble starting the chainsaw, take it to a professional for servicing.

Check The Air Filters

If your chainsaw won’t start, one possible reason is that the air filter is dirty. The air filter prevents dirt and debris from getting into the engine, so if it’s clogged, the engine can’t run properly.

To clean the air filter, remove it from the chainsaw and wash it with soap and water. Be sure to let the air filter dry completely before putting it back in the chainsaw.

Once you’ve cleaned the air filter, try starting the chainsaw again.

Is It Too Cold?

Another possible reason why your chainsaw won’t start is that it’s too cold. Chainsaws are designed to operate in temperatures above freezing, so if it’s too cold, the chainsaw might not start.

Is It Too Cold?

If it’s cold outside, try starting the chainsaw indoors where it’s warmer. If the chainsaw starts indoors, the cold weather is likely to cause the problem.

Ignition Coil

The ignition coil is responsible for generating the spark that ignites the fuel. If the ignition coil is defective, the chainsaw won’t start.

To check the ignition coil, remove it from the chainsaw and test it with an ohmmeter. If the coil is damaged, it will need to be replaced.

Once you’ve checked or replaced the ignition coil, try starting the chainsaw again.

Recoil Starter

If the ignition coil is working properly, the next thing to check is the recoil starter. The recoil starter is responsible for turning over the engine when you pull the cord. If it’s not working properly, the chainsaw won’t start.

Recoil Starter

To check the recoil starter, remove it from the chainsaw and inspect it. If the recoil spring is broken, it will need to be replaced.

Once you’ve checked or replaced the recoil starter, try starting the chainsaw again.

Compression Release

The compression release is a valve that helps reduce the amount of compression in the engine. If the compression release is stuck, it can prevent the engine from starting.

To check the compression release, remove it from the chainsaw and inspect it. If the valve is stuck, clean it with a wire brush. Be sure to lubricate the valve with engine oil before putting it back in the chainsaw.

Fuel Line

The fuel line carries fuel from the tank to the carburetor. If the fuel line is cracked or leaking, it will need to be replaced.

To check the fuel line, remove it from the chainsaw and inspect it for damage. If the fuel line is damaged, it will need to be replaced.

Rewind Spring

The Rewind spring is responsible for rewinding the starter cord when you release it. If the Rewind spring is broken, the starter cord won’t rewind and the chainsaw won’t start.

If the starter cord doesn’t wind properly, you’ll need to replace the Rewind spring.

Once you’ve replaced the Rewind spring, try starting the chainsaw again.

 Blocked Or Clogged Spark Arrestor

The spark arrestor is a screen that helps prevent sparks from escaping from the muffler. If the spark arrestor is clogged, it can prevent the engine from starting.

 Blocked Or Clogged Spark Arrestor

To clean the spark arrestor, remove it from the chainsaw and brush it with a wire brush. Be sure to clean any debris out of the muffler as well.

Once you’ve cleaned the spark arrestor, try starting the chainsaw again.

Electric And Battery-Powered Chainsaws

If you have an electric or battery-powered chainsaw, there are a few things you can check if the chainsaw won’t start.

First, make sure that the power cord is plugged in and that the outlet is working. If the outlet isn’t working, you’ll need to reset the circuit breaker or replace the fuse.

Next, check the battery. If the battery is dead, you’ll need to charge it or replace it.

Fuse: If your chainsaw has an electrical problem, one possible reason is a blown fuse. If the fuse is blown, it will need to be replaced.

To check the fuse, remove it from the chainsaw and inspect it. If the fuse is blown, it will need to be replaced.

Finally, make sure that the chainsaw is properly lubricated. If the chainsaw isn’t lubricated, it can cause the motor to overheat and shut off.

If you’ve checked all of these things and the chainsaw still won’t start, take it to a qualified technician for repair.

Conclusion

There are several reasons why your chainsaw won’t start. In most cases, the problem can be fixed by checking or replacing the spark plug, recoil starter, or fuel line. However, if the problem persists, you may need to take the chainsaw to a qualified technician for repair.
