If your Stihl chain saw is hard to start, there are a few troubleshooting steps you can take to fix the problem. Firstly, check the fuel level and make sure it is fresh and mixed correctly. Next, clean or replace the air filter to ensure proper air flow. Additionally, check the spark plug for any damage or wear and replace if necessary. If the problem persists, try adjusting the carburetor or cleaning the carburetor jets. Lastly, make sure the saw has enough compression by performing a compression test. By following these steps, you should be able to troubleshoot and fix a Stihl chain saw that is hard to start.
Regular maintenance is key to ensuring that your Stihl chainsaw starts easily every time. Proper storage techniques can also help with starting after extended periods of non-use. Difficulties starting the chainsaw may be caused by issues with gasoline storage, spark plugs, or incorrect starting procedures. Fortunately, these issues can be resolved by following some troubleshooting steps.
Step 1: Check the Gasoline
If your chainsaw is hard to start, check the gasoline in the tank. If the saw has not been used in over a month, discard the old gasoline and replace it with fresh fuel. It’s a good practice to start each season with fresh gasoline.
Step 2: Inspect the Spark Plug
If the engine is still hard to start, check the spark plug. Use a socket set to remove the spark plug and clean it if it’s dirty. Ensure that the electrode gap is 0.02 inches on the Stihl 026 model. Replace the spark plug after every 100 operating hours. If the spark plug is not a light-tan color, it may indicate engine problems that require professional servicing.
Step 3: Start the Saw Correctly
If the chainsaw is still difficult to start, ensure that you are starting it correctly. If the engine is cold, turn on the choke and switch to the warm start position as soon as it starts running. Quickly press the throttle trigger. If it’s a new engine, prime the fuel line by pulling the starter grip several times before starting the engine.
FAQ
1. Why is my Stihl chainsaw difficult to start?
There could be several reasons why your Stihl chainsaw is hard to start. Firstly, check the spark plug to ensure it is clean and properly gapped. A dirty or damaged spark plug can prevent the engine from starting. Secondly, check the fuel filter and air filter for any clogs or blockages. A dirty fuel or air filter can restrict the flow of fuel or air to the engine, making it difficult to start. Lastly, make sure you are using the correct fuel mixture and that the carburetor is properly adjusted. Incorrect fuel mixture or carburetor settings can also cause starting issues.
2. How do I clean the spark plug on my Stihl chainsaw?
To clean the spark plug on your Stihl chainsaw, first, remove the spark plug wire from the spark plug. Use a spark plug wrench to remove the spark plug from the engine. Inspect the spark plug for any signs of damage or excessive wear. If the spark plug appears dirty or fouled, use a wire brush or spark plug cleaner to remove any carbon deposits. Make sure the spark plug gap is set to the manufacturer’s specifications. Reinstall the spark plug and tighten it securely. Finally, reconnect the spark plug wire to the spark plug.
3. How often should I replace the air filter on my Stihl chainsaw?
The frequency of air filter replacement on your Stihl chainsaw depends on the operating conditions and usage. However, as a general guideline, it is recommended to inspect and clean the air filter after every 10 hours of use. If the air filter is excessively dirty, damaged, or worn out, it should be replaced. Regular maintenance and cleaning of the air filter will ensure proper airflow to the engine and help prevent starting issues.
4. What should I do if my Stihl chainsaw floods?
If your Stihl chainsaw floods, it means there is an excess amount of fuel in the engine. To remedy this, first, remove the spark plug wire from the spark plug. Use a towel or cloth to wipe off any excess fuel around the spark plug area. Open the choke fully and pull the starter cord several times to clear out the excess fuel. Let the chainsaw sit for a few minutes to allow any remaining fuel to evaporate. Reinstall the spark plug and spark plug wire, and then attempt to start the chainsaw again.
5. Why does my Stihl chainsaw stall after starting?
There are a few possible reasons why your Stihl chainsaw may stall after starting. One common cause is a clogged fuel system. Check the fuel filter and fuel lines for any blockages or restrictions. Clean or replace them if necessary. Another possible reason is a malfunctioning ignition system. Check the spark plug and ignition coil for any issues. Additionally, a carburetor that is not properly adjusted or needs cleaning can also cause stalling. Ensure the carburetor is adjusted according to the manufacturer’s specifications and clean it if needed.
