The humble push mower is a staple in many gardens and lawns around the world. It’s a reliable and environmentally friendly way to keep your grass trimmed and looking its best. However, one of the most crucial components of a push mower is the spark plug. Without a functioning spark plug, your mower won’t start, and you’ll be left with a patchy, overgrown lawn. But what size spark plug do you need for your push mower? In this comprehensive guide, we’ll explore the importance of spark plugs, how to choose the right one, and provide a list of the most common spark plug sizes for push mowers.
Why Spark Plugs Are Important
A spark plug is responsible for igniting the fuel-air mixture in your mower’s engine, allowing it to run smoothly and efficiently. Without a spark plug, the engine won’t receive the necessary spark to ignite the fuel, and it will stall or fail to start. Spark plugs are also responsible for cleaning the engine by removing deposits and debris that can build up over time.
How to Choose the Right Spark Plug
Choosing the right spark plug for your push mower is crucial to ensure it runs smoothly and efficiently. Here are a few factors to consider:
| Engine Type | Spark Plug Size |
| Small Engine (less than 200cc) | 10mm or 12mm |
| Medium Engine (200cc to 400cc) | 14mm or 16mm |
| Large Engine (over 400cc) | 18mm or 20mm |
Another important factor to consider is the type of spark plug you need. There are two main types of spark plugs: NGK and Champion. NGK spark plugs are known for their high-quality and durability, while Champion spark plugs are more affordable and still provide good performance.
