ABSTRACT:
A preferred embodiment includes a spark plug supporting assembly for supporting a spark having a longitudinal axis such that the gap-defining end of the ground electrode of the spark plug extends substantially perpendicular to the longitudinal axis. A blade assembly is operably associated with the spark plug supporting assembly for splitting the gap-defining end of the ground electrode into at least first and second prongs of substantially equal size. The blade assembly includes a blade member having a longitudinal axis oriented substantially perpendicular to the longitudinal axis of the spark plug. An actuating member is operably associated with the blade assembly to displace the same between a storage position and an operating position while the gap-defining end of the ground electrode is positioned substantially perpendicular to the longitudinal axis of the spark plug.
