Spark plug
Spark plugs are rather simple devices operating on electricity generated by the running engine. It’s not quite perpetual motion because another energy source (pulling a start cord, or a battery for some riding mowers) is needed to start the motor. Once the motor is running, however, it generates electricity to power the spark plug.
Anode
The anode is a small post covered by a metal tongue on one end of the spark plug. When the spark plug is screwed into the motor, the anode is positioned inside the cylinder housing. The anode has two parts: the center electrode (the post) and the ground electrode (the tongue.)
Gap tool
A simple tool is used to set the spark plug gap. A round piece of metal has several different pieces of wire attached. Each wire is a different thickness ranging from one to six millimeters. A spark plug’s proper gap is written on the packaging. Use the correct wire to open or close the gap so the wire passes between electrodes with no clearance.
Faulty gap
Shipping and handling can cause new spark plugs to get bumped and the ground electrode to move. Always check the gap before installing new spark plugs. Gaps can get misadjusted by dropping the spark plug on its ground electrode, by engine heat causing the ground electrode to slightly move or by constant use eating away part of the ground electrode.
