Things You'll Need
The Craftsman snow blower makes it easy to remove snow without needing a snow shovel. The snow blower uses a small gasoline engine that uses a spark ignition system. The spark plug ignites the fuel causing the combustion process. Craftsman recommends inspecting the spark plug every 100 operating hours, or every year. You should replace the spark plug if the porcelain is cracked or the electrode on the end is burned or fouled. You can replace the spark plug at home with a few basic tools.
Turn off the engine and allow it to cool before starting the procedure. Remove the spark plug wire by pulling it gently with your fingers. Clean around the spark plug with a rag to remove any dirt or debris.
