In this article, we'll guide you through the common issues that may cause your Stihl leaf blower to malfunction and provide you with step-by-step solutions to get it up and running again.
Pre-Start Checks
Before diving into complex troubleshooting, make sure you've covered the basics. Perform the following pre-start checks to ensure you've not overlooked something simple:
Check the power switch is in the "on" position. It may seem obvious, but it's easy to overlook.
Verify the fuel tank is not empty. If it is, refill it with the recommended type and amount of fuel.
Ensure the spark plug wire is securely connected to the spark plug.
Check the air filter is clean and not clogged. A dirty air filter can prevent the engine from starting.
Fuel-Related Issues
Fuel-related problems are common causes of a Stihl leaf blower not starting. Here are some potential issues to investigate:
Old or stale fuel: Fuel can break down over time, causing issues with engine performance. Try draining the old fuel and refilling with fresh fuel.
Fuel mixture: If you're using a two-stroke engine, ensure the fuel-to-oil ratio is correct. Consult your owner's manual for the recommended mixture.
Clogged fuel filter: Check the fuel filter for blockages or debris. Clean or replace it as needed.
Fuel line blockages: Inspect the fuel line for kinks, cracks, or blockages. Replace the fuel line if necessary.
Spark Plug Issues
A faulty spark plug can prevent your Stihl leaf blower from starting. Try the following:
Remove the spark plug and clean it with a spark plug cleaner. Reinstall the spark plug and try starting the engine again.
If cleaning the spark plug doesn't work, replace it with a new one. Make sure to gap the new spark plug correctly.
Air Filter Issues
A dirty or clogged air filter can reduce airflow, making it difficult or impossible to start the engine. Try the following:
Clean the air filter with compressed air or a soft brush. Reinstall the air filter and try starting the engine again.
If the air filter is damaged or cannot be cleaned, replace it with a new one.
Ignition System Issues
Problems with the ignition system can prevent the engine from starting. Check the following:
Spark plug wire: Ensure the spark plug wire is securely connected to the spark plug and the ignition coil.
Ignition coil: If the spark plug wire is secure, try replacing the ignition coil.
Carburetor Issues
The carburetor regulates the fuel-to-air mixture. If it's clogged or malfunctioning, the engine won't start. Try the following:
Clean the carburetor with a carburetor cleaner. Reinstall the carburetor and try starting the engine again.
If cleaning the carburetor doesn't work, consider replacing it.
Other Potential Causes
While less common, the following issues can still cause your Stihl leaf blower to malfunction:
Worn or damaged starter cord: If the starter cord is worn or damaged, it may not engage the engine properly. Replace the starter cord if necessary.
Bad spark plug cap: The spark plug cap may be cracked or damaged, preventing the spark plug from firing. Replace the spark plug cap if necessary.

To minimize the risk of your Stihl leaf blower not starting, perform regular maintenance:
Regularly clean the air filter and spark plug.
Check and maintain the correct fuel-to-oil ratio.
