What is the typical setting for the spark gap on a spark ignition system?

The typical setting for the spark gap on a spark ignition system is generally around 1/8 inch. This specific distance is commonly recommended because it provides an optimal balance between reliable ignition and the efficiency of the system. A spark gap that is too wide may lead to higher voltage requirements for ignition, increasing the risk of incomplete combustion or difficulty in starting the engine. Conversely, a gap that is too narrow might result in excessive wear on the ignition components or lead to misfires. Therefore, maintaining the spark gap around 1/8 inch helps ensure that the ignition system functions effectively, providing reliable starts and efficient performance in gas-powered equipment.
