schematic blueprint of a typical lawnmower shows spark plug and blade assembly. The plug holds a candle that melts a type of fuel Depending on the type of fuel (gas, liquid) the spark plug actually produces a type of high-voltage current.
Commonly, if the plug is loose it’s usually a positive wire coming out of the plug or the spark plug is missing altogether. You’ll find that the oil level is extremely low at this time. As the engine runs, the oil drips out of the seat on top of the lawnmower. You’ll want to add new oil, if possible, before starting the mower. If you find that the lawnmower produces too much smoke, this means that the plug is too close to the spark plug hole and will be lost.

From the spark plug heater to the blades, spark plug fires are usually caused by small debris intake on the spark plug or too much oil. Both can be easily fixed, the blades simply need to be kept clean. Another cause of spark plugs being ineffective is the dry cutting but usually just cutting grass leaves caused by an algae build-up. Running the lawnmower at a slow speed once a week will help to avoid this problem. It’s also very important to keep the blades of your mower sharp enough to start the blade compartment in the off states like Sedona, Arizona.
It’s relatively simple to replace a spark plug by yourself. Some recommended places to buy a plug are hardware stores like Home Depot and Lowes. But if you’re unable to find it just cut off the spark plug tube at the end of the BBQ grill and stick in a new one. You can usually purchase one at Lowes for under $20. Also, you can replace the blades themselves fairly cheaply. After 3 months they are only a $20 replacement part. You simply take the cutting tip off the blade and slide the new part into place. When replacing blades, check the distributor of the spark plug underneath the mower and on the edge of the cutting deck.
The next area you can focus on, if there is dirt collected on the blades, is to clean off all the dirt. This is the most time-consuming because you have to work on both sides of the blades to clean the dirt away. Always use a heavy scrub brush to help loosen the dirt. A mains power pressure washer can be used or a garden hose with low pressure and a scrubbing attachment will work.
Once cleaned all that’s left is to fill the mower with gas or an oil mixture and test the lawnmower. Fill the gas tank with enough gas to keep the engine running and good. Turn the mower on and try to cut a 2-inch lawn in the fastest way possible. If you find that the lawnmower cycles over and runs itself, the blades didn’t have enough fuel or were dirty the blades are dirty also. One of the best tips we can give is to take the blade out completely, that way the dirt can be cleaned out efficiently and you can get good cleaning of all the blades. Being sure that the blades are sharp is also important because dull blades can cause more stress on the engine. Try cutting some of the grass off of the blades and see how the engine works.
