Abstract
An ignition device for an engine is removable without removing the cylinder head cover, for gaining access to the spark plug. A case has a lower portion releasibly fitted around a spark plug mounted to a cylinder head of the engine. First and second bobbins having coils wound thereon are mounted concentrically in the case and a C-shaped core is positioned outside of the case and has distal ends fitted in the bobbins. An ignition head cover removably mounted to the cylinder head cover of the engine supports the core when the lower portion of the case is fitted around a spark plug.
