The spark plugs are typically located at the top of the cylinder head. The piston moves down the cylinder where it take in a combination of air and fuel. Next, the piston travels back up to the spark plug, compressing the mixture.
In most modern cars, the spark plugs are located near the top of the engine, firmly bolted into the cylinder head. Keep in mind that they might be buried under a mess of wires, or hidden by a plastic cover.
Changing your lawn mower`s spark plugs doesn`t take a lot of tools. The job can be done with a regular socket or a wrench and spark plug socket. Along with this, you will also need a spark plug gap gauge.
Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor if you do it yourself. In most cases it`s a simple job that will help to maintain peak performance and the highest possible gas mileage.
Place the socket around the spark plug and turn the socket counterclockwise. The spark plug should unscrew easily. If you are having problems removing a spark plug that is too tight, stop before you break it off. You can put a bit of dedicated penetrating oil to help loosen it.

I have a Crafstman Riding mower model #917.273643. That ran fine one second, I shut it off for five minutes. When I went to start it back up it wouldn’t start. Cranks fine, checked the wires, fuse, and spark plug. The plug was dirty so I cleaned it. But I am not getting any spark. I bought a new plug still no spark. I also checked the plug on another motor and I had spark so the plug wasn’t bad. Any suggestions on how to troubleshoot this or what may be wrong?
