1. Identify the source of the leak. Check for any visible cracks or damage to the carburetor body, gaskets, or fuel lines.
2. Clean the carburetor. Remove the carburetor and clean it thoroughly with carburetor cleaner and compressed air. Pay close attention to the float bowl, jets, and needle valve.
3. Check the float. Ensure that the float moves freely and is not stuck. The fuel level in the float bowl should be about 1/4 inch below the bowl's top.
4. Replace any damaged parts. If you find any damaged gaskets or fuel lines, replace them with new ones. Make sure to use genuine Toro parts for best performance and longevity.
5. Reassemble the carburetor. Once all the parts are clean and any damaged components are replaced, reassemble the carburetor and reinstall it on the snowblower.
6. Test the carburetor. Start the snowblower and check for leaks. If there are no leaks, you have successfully stopped the carburetor from leaking.
Please note that if you are not comfortable performing these steps or do not have the necessary tools, it is recommended to take the snowblower to a certified technician for repair.
