I recently purchased a 1 1/2 HP Economy hit-and-miss engine that has
an igniter. I have read some as to how it works, but I can't seem to
find any information as to how to hook up the battery and coil to it.
I see the point to which the high voltage lead of the coil is attached
as well as that where the negative side of the coil is attached. I can
find no point, however, where the negative battery lead is indicated
to be connected. Is it simply connected to any point on the block or
am I missing something?There is no wiring diagram in the original
manual and I can't find anything specific online.

I would appreciate feedback from someone who is familiar with these
devices. Thanks.
