Deep in the heart of bad spark plugs there is a desire to lawn mower. It is a phenomenon as old as the spark plug itself. The original inventors of the spark plug thought they had it just right when they had the little ceramic and steel chunk in their hands, but they had overlooked one detail, the most important detail of all. The detail that doesn't surface until the good spark plug... goes bad. Anyone in posession of a spark plug must remain vigilant lest the good plug transform into a bad one. As soon as the plug has gone bad, it is too late to save its fate. The process starts when the plug realizes its estranged situation, sitting in an engine block, all alone in the world, expected to take the heat day after day, to put up with quick orders, extreme pressure, and the occassional scraping up and twisting around, and perhaps most demanding of all, keep its vibrant spark the whole time. The process starts slowly. The concept of "lawn" will form in its mind. Then the word "mower" will also take shape. The two get combined into the most evil verb of all, "lawn mower." The plug will have an epiphany of sorts, where all the pieces of the puzzle will fall into place, one by one evil piece. And then it happens. It lawn mowers. You don't want to be around when it lawn mowers. You don't even want to ask what it does when it lawn mowers, for that question is nearly as gruesome as the answer itself. Not to mention that no one is around to answer, because all witnesses to lawn mowering suffer such a diabolical and tortuous fate. Why, you ask, why, does a bad spark plug lawn mower? The answer to your question is that no one can say exactly why a bad spark plug lawn mowers. All that can be said is that they do, and, God have mercy on our souls, you don't want them to. I write this with the utmost urgency that, You. Do. Not. Let. Your. Good. Spark. Plug. Go. Bad.
Ordinary home lawnmowers have only one spark plug.
take the spark plug out of the head. then put the spark plug wire back on the spark plug. ground the plug on the engine you can do this by putting the plug any where there is metal and lay it on it. then turn engine over and see if you have spark. if not then do the same thing with just the wire by putting a Philips screw driver in place of the plug, ground it turn over the engine see if there is a spark if their is the plug is bad. if not then the coil or flywheel is bad more than likely it is the coil
Would you use lawn mower plugs in your car?? NO!!!!
Some lawn mowers are called self propelled because they require no electric plug to turn on. They have batteries in them that power them and make them work.
You can check for spark by removing the plug wire from the spark plug and holding it about 1/4 inch from ground. Have some one crank the engine or pull the starter rope and look for a spark to jump from the spark plug wire to ground. DO NOT hold the wire with your bare hands since you will get shocked. If you have spark there, remove the spark plug and insert it into the end of the spark plug wire and do the same procedure. If there is no spark, the plug is bad. If you have spark, the problem lies elsewhwere.
One standard push mowers they help make the spark for the spark plug. On riding mowers and electric start push mowers they do the same and there is another set of magnets that charge the battery.
