Hi Norm

Haven't got around to it yet but I have no doubt it will work.

The voltage you need to zap a spark plug is pretty constant over models, and timing of zap is controlled by coil position, so I can't see any reason it wouldn't trigger properly

Remember, the original Atom modules https://pickersyard.weebly.com/atom-universal-electronic-ignition-module.html

Looks like they had a few different types. I initially thought 2 stroke v 4 stroke, however briggs have a wasted spark anyway don't they?
