The spark plug for your Troy Bilt lawn mower should be located near the top of the engine, typically near the cylinder head of the engine. It is usually secured by a spark plug wire or bracket, which can sometimes be difficult to spot.
To make it easier to find, try shifting the mower to the side and checking around the back of the engine. Make sure to disconnect the spark plug wire before doing any servicing on the spark plug. If you are still having trouble locating it, refer to the owner’s manual or call a professional.
How do I know the size of my spark plug?
In order to determine the size of your spark plug, the first step is to consult your owner’s manual or service manual, which should list the size of the spark plugs used in your particular make and model of vehicle.
Alternatively, using the vehicle’s VIN number, as well as your engine size and year of production, you can look up the correct size spark plug on a parts website.
Once you know what size you need, you must then measure the current spark plug to determine if it needs to be replaced. To do this, you need to use a spark plug gauge. This tool contains a variety of hole diameters; you simply insert the plug between two of the holes and if it fits snugly, then the size of the spark plug will be the one on the tool that the gap between the two holes represents.
You must also examine the reach of the spark plug, as this defines how far the plug reaches out of the engine cylinder before the electrodes make contact. Once again your appropriate owner’s manual will define this measurement, or you can use an inch/metric tape measure to measure the distance from the top of the spark plug to the edge of the cylinder.
Knowing the size and reach of the spark plug is key to choosing the right one when replacing it, and is essential to the efficient and safe operation of the vehicle engine.
What size are mower spark plugs?
The size of mower spark plugs varies based on the make and model of the mower. Generally speaking, most mower spark plugs come in either a 14 mm or 18 mm thread size. Before buying a spark plug, it is necessary to consult the manufacturer’s specifications, as the type and size of spark plug required can vary by mower model.
Additionally, many mower spark plugs can be identified by their part number, which should be printed on the side of the spark plug and easily decipherable by referencing the manufacturer’s website or manual.
What size is a Briggs and Stratton spark plug?
The size of a Briggs and Stratton spark plug depends on the model of the engine. For example, the most common spark plug for a Briggs and Stratton engine is the Champion RC12YC and RC14YC; these are both 14mm thread size with a 19mm reach and a 5/8″ hex size.

Generally, spark plugs should be installed in the firing order specified by the manufacturer, but some engines may require a specific order or staggered firing order. When replacing spark plugs, it is important to use the correct type and gap size to ensure smooth engine performance.
Additionally, when installing the plugs, they should be tightened to the specified torque and should be properly gap adjusted to ensure engine performance.
What are the 3 types of spark plug?
There are three main types of spark plugs, based on the type of end connector: surface gap plugs, projected gap plugs, and tapered seat plugs.
Surface gap plugs have a ground electrode connected to the terminal nut, which sits flush against the mounting shell surface. This type offers good performance over a range of temperatures, but is more prone to electrical leakage due to its larger surface area.
Projected gap plugs feature a center electrode protruding from the end of the terminal nut. This can reduce the spark plug size, but performance is more temperature-sensitive than surface gap plugs and electrical leakage is more common.
Tapered seat plugs have a center electrode that is shaped like a tapered cone. This provides improved heat dissipation, but the cone shape can make them more difficult to install due to their narrower contact surface.
Each of these spark plug types is suitable for a different application or use. Depending on the type of engine and its expected operating requirements, the type of spark plug best suited to the application will vary.
Generally, surface gap plugs offer good all-around performance, while tapered seat plugs are the best choice for high-compression or high-temperature engines, and projected gap plugs work best with lower-temperature, low-compression engines.
How are the spark plugs numbered?
Spark plugs are typically numbered based on their firing order, which is the order in which the pistons in the engine fire. Generally, the engine will have a cylinder numbered 1 through 4 (in the case of a 4-cylinder engine) or 1 through 6 (in the case of a 6-cylinder engine).
Spark plug 1 is attached to cylinder 1 and it fires first, followed by spark plug 2 on cylinder 2, then spark plug 3 on cylinder 3, etc. The number of spark plugs for an engine is usually equal to the number of cylinders in the engine.
It’s important to keep the spark plugs in their proper firing order, so the engine runs smoothly. In some cases, the firing order for spark plugs of the same engine may vary depending on the manufacturer or even the model year, so it’s important to refer to specific instruction manuals for the engine in question.
Is there a specific spark plug for lawn mower?
The answer is yes, there is a specific spark plug for lawn mower. The type and size of spark plug that is best suited for a lawn mower depends on the manufacturer and make of your lawn mower.
Generally speaking, garden tractors, riding mowers and zero-turn mowers use a Champion RC12YC Spark Plug or equivalent. Push mowers typically use a Champion RJ19LM (or equivalent) spark plug. To ensure that you’re obtaining the correct spark plug for your lawn mower, it’s best to refer to the owner’s manual for specific recommendations.
When replacing a spark plug, it’s important to use only genuine manufacturer-approved parts. Replacing the spark plug with an equivalent that offers different specifications will lead to poor engine performance, a lack of power, and other issues.
It is also important to use a spark plug that is created specifically for your lawn mower’s engine. Spark plugs with different thread seat designs and/or thread reach may damage the engine.
It is recommended that you inspect and replace the spark plug at least once every season, or if it’s necessary sooner due to poor performance or misfire.
Can the wrong spark plugs ruin an engine?
Yes, the wrong spark plugs can ruin an engine. Spark plugs create the spark that is necessary for an engine to fire and run properly. If the wrong spark plug is used, it could lead to an incorrect air-fuel mixture entering the engine.
This can lead to incomplete combustion, which can cause a build-up of carbon deposits in the cylinder. This can result in misfires, a decrease in fuel efficiency and deterioration of the engine performance.
If it is not addressed, it can even cause serious engine damage such as seized pistons, damaged valves or cracked cylinder heads. Therefore, it is important to make sure you are using the right spark plugs in order to keep your engine running effectively and efficiently.
Do expensive spark plugs make a difference?
Expensive spark plugs can make a difference in some circumstances, but most of the time the difference will be relatively minor. Spark plugs are a relatively simple component and, of course, the more expensive spark plugs will usually be better quality, but even the cheapest will usually get the job done.
However, depending on the type of engine, expensive spark plugs may enable a more effective combustion, and in some cases provide better fuel economy and/or more power. When comparing spark plugs, the two main factors to consider are gap size and electrode material.
The gap size should be specific to the particular engine and the electrode material will determine how long it will last and how much energy it will transfer. Expensive spark plugs may also include higher quality electrode materials that will last longer and provide better performance than cheaper ones.
Generally speaking, more expensive plugs are more likely to come with higher quality materials, while cheaper plugs may sacrifice the quality of materials slightly.
