    Would leaving one plug in the block and connected and the attaching my spark gap tester to the other be the right way to check for spark on this?

    Thanks

    That ought to work. Another way is use two spark gap testers. Another way is ground one plug wire. What won’t work is leave one plug wire disconnected and dangling in air.

    BTW, the kind of coil I am describing is not at all unusual. It is what is on my Honda motorcycle. It is also what is used on many antique opposed twin outboards. Nothing new under the sun, they say.
