Troubleshooting a Stihl Chainsaw That Won’t Stay Running

If your Stihl chainsaw won’t stay running, there are a few things you can check to troubleshoot the problem.

1. Check the fuel

The most common reason for a chainsaw not to stay running is a problem with the fuel. Make sure that you are using the correct type of fuel for your chainsaw. Stihl chainsaws require a mixture of gasoline and oil. The oil-to-gas ratio should be 1:50.

2. Check the spark plug

The spark plug is responsible for igniting the fuel in the chainsaw’s engine. If the spark plug is dirty or damaged, it will not be able to properly ignite the fuel, and the chainsaw will not run.

To check the spark plug, remove it from the chainsaw and inspect it for damage. The electrodes should be clean and free of deposits. If the spark plug is damaged, replace it with a new one.

3. Check the air filter

The air filter prevents dirt and debris from entering the chainsaw’s engine. If the air filter is clogged, it will restrict the flow of air to the engine, and the chainsaw will not run properly.

To check the air filter, remove it from the chainsaw and inspect it for dirt and debris. If the air filter is dirty, clean it with a brush or replace it with a new one.

4. Check the carburetor

The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is not adjusted properly, the chainsaw will not run properly.

To check the carburetor, you will need to remove it from the chainsaw and adjust the fuel and air mixture. If you are not comfortable doing this, you can take the chainsaw to a qualified service technician.

5. Check the engine

If you have checked all of the above and the chainsaw still will not run, there may be a problem with the engine itself. This could be a problem with the valves, pistons, or other components.

If you suspect that there is a problem with the engine, you should take the chainsaw to a qualified service technician.
