Engine just has the coil and the magnet in the flywheel to make the spark. Have you tried removing the black kill wire from the coil, and checking for spark?

Expert:  Curtis B. replied 11 months ago.

How are you checking the spark? Spark plug removed, and grounded to the metal of the engine, while cranking?
