This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.
