Getting Started: A Thorough Cleaning

What You’ll Need:
- A Garden Hose: Start by rinsing off the exterior of the mower with water.

- Use a Sharpener: If you’re comfortable, you can use a blade sharpener. Just be sure to follow the manufacturer’s instructions.
- Balance the Blades: After sharpening, ensure the blades are balanced to prevent vibrations.
Inspecting the Engine: A Vital Step in Lawn Mower Restoration
The engine is the heart of your lawn mower, so it’s essential to give it a thorough inspection. This will help you identify any potential problems and get your mower running smoothly again.
What You’ll Need:
- A Screwdriver: Use a screwdriver to remove the spark plug and access other engine components.
- A Spark Plug Wrench: Use a spark plug wrench to remove and install the spark plug.

Engine Inspection Tips:
- Check the Spark Plug: The spark plug should be clean and free of carbon buildup. If it’s fouled, you’ll need to clean or replace it.
- Inspect the Air Filter: The air filter should be clean and free of debris. If it’s dirty, you’ll need to clean or replace it.
- Examine the Carburetor: The carburetor should be free of dirt and debris. If it’s clogged, you’ll need to clean it or replace it.
