Fuel Leaking On Ms 181

If your MS 181 chainsaw is leaking fuel under the gas tank while it is running, this could indicate a problem with the fuel system or the fuel lines. Here are some steps you can take to troubleshoot and fix the issue:

1. Check the fuel lines: Look for any cracks, holes, or other damage to the fuel lines. Replace any damaged lines immediately.
2. Inspect the fuel filter: The fuel filter may be clogged or dirty, preventing proper fuel flow. Clean or replace the fuel filter if necessary.
3. Tighten the fuel cap: A loose or damaged fuel cap can cause fuel to leak out. Make sure the fuel cap is tightened securely.
4. Check the carburetor: The carburetor may be dirty or damaged, causing fuel to leak out. Clean or rebuild the carburetor if necessary.
5. Replace the fuel tank: If the fuel tank itself is damaged, it may be leaking fuel. Replace the fuel tank if necessary.

It is recommended that you bring your chainsaw to a professional if you are not comfortable troubleshooting and repairing the fuel system yourself. A qualified technician will be able to diagnose and fix the issue safely and effectively.
