You were correct about the fact that the coil would work on a different type of engine- whether mower, chainsaw or other.

As I thought, the lower resistance coil made all the difference in producing spark.

So so pleased about that.
I initially bought the ignition module to try out on a PT Victa, but that did not eventuate, and when attempts at getting the points to go, failed, I thought it was worth the conversion.
Glad I did.
