Testing The Mower After Fix
Start the mower engine carefully to check if it runs smoothly. A quick start shows the fuel filter is clear and fuel flows well. Listen for any odd noises or sputtering sounds.
Look closely around the fuel filter for leaks. Fuel spots or wet areas mean the filter or connections are not sealed right. Tighten clamps or replace damaged parts if needed.
