Here's how to find the right spark plug:
1. Locate your engine's model number. This is usually found on a metal tag attached to the engine, often near the valve cover.
2. Use the model number to search for a spark plug recommendation online. You can use Briggs & Stratton's website or a reputable parts supplier like Amazon.
3. Verify the spark plug specifications. Ensure the heat range and thread size are correct for your engine.
Important: Always refer to your engine's owner's manual for the most accurate spark plug recommendation.
