No, all lawn mower spark plugs are not the same size. In fact, there are many different sizes and types of spark plugs available on the market today. Depending on the make and model of your lawn mower, you will need to find the correct size and type of spark plug for your machine.
If you’ve ever gone to buy a lawn mower spark plug, you may have noticed that there are different sizes available. So, are all lawn mower spark plugs the same size?
The answer is no, they are not.
Lawn mower spark plugs come in different sizes because different lawn mowers have different engine sizes. The size of your lawn mower’s engine will determine the size of spark plug that you need.
Generally speaking, the larger the engine, the larger the spark plug.
So, if you have a small push mower, you’ll need a small spark plug. On the other hand, if you have a large riding mower, you’ll need a large spark plug.
Of course, it’s always best to consult your owner’s manual to be absolutely sure which size spark plug your lawn mower needs.
But now you know that not all lawn mower spark plugs are the same size!
Which spark plug to use for your mower
Are Lawn Mower Spark Plugs Universal?
Spark plugs are an important part of any lawn mower, and it is important to choose the right ones for your model. While there are some universal spark plugs on the market, they may not be the best choice for your lawn mower. It is important to consult your owner’s manual or a professional before purchasing spark plugs.
How Do I Know What Size Spark Plug I Need for My Lawn Mower?
There are a few ways to determine what size spark plug you need for your lawn mower. The first way is to consult your mower’s owner’s manual. The manual will usually have a section that lists the recommended spark plugs for your mower model.
If you don’t have your owner’s manual, you can also find this information on the manufacturer’s website.
Another way to determine the right spark plug size for your lawn mower is to measure the diameter of the current spark plug in use. Most spark plugs have their size printed on them, so this should be easy to do.
Once you know the diameter of the current plug, simply find a replacement with the same dimensions.
If you’re still unsure about which size spark plug to get for your lawn mower, it’s best to err on the side of caution and go with a slightly larger size. It’s better to have a slightly too-big spark plug than one that’s too small and doesn’t fire properly.
What Size Spark Plug Does a Lawn Mower Take?
The size of spark plug a lawn mower takes is typically determined by the model and make of the lawn mower. However, there are some general tips that can help you determine the right size spark plug for your lawn mower.
For most Briggs & Stratton engines, the right spark plug will be an RN14YC.
This is a 14mm, 3/4-inch reach plug with a 5/8-inch hex and a gasket seat.
For Kohler engines, the correct spark plugs will depend on the model number of your engine. For example, Kohler Courage engines use an NGK BPR5ES while Kohler Command PRO engines use an NGK RC12YC.
If you’re unsure about what size or type of spark plug to use for your lawn mower, consult your owner’s manual or contact the manufacturer directly.
What Happens If You Put the Wrong Size Spark Plug in a Lawn Mower?
If you put the wrong size spark plug in a lawn mower, it may not start or run properly. The engine may misfire, and the mower may emit black smoke from the exhaust. In some cases, the wrong size spark plug can damage the engine.
