Steptoe, you are just replacing one ignition system with another, without changing the spark plug position, mixture, compression ratio, etc. Furthermore you are not changing the coil, so you are just replacing one method for triggering the coil with another method. Provided that ignition timing is not changed, and neither trigger provides a higher peak primary voltage than the other, the two systems should give the same result at reasonable engine speeds (at astronomical engine speed the points system might run into mechanical limitations, but this is unlikely with a single cylinder engine unless you were talking about chainsaw-like speeds).
In practice there may be a small difference in ignition timing, because one system uses the position of the module relative to the flywheel magnets to trigger the ignition, while the other uses the points. The points give a very stable trigger point, while the voltage induced by the flywheel magnets may have a built-in time delay which might be a constant amount of time rather than a constant number of crankshaft degrees. You would need to test that by using a timing light to find where ignition actually occurs with each trigger source at various engine speeds. The exact outcome might vary depending on exactly how the electronic trigger is designed.
If you were trying to get maximum power from the engine one of the first things you would do would be to find a way to fit a variable ignition advance system so that the ignition timing would be right at high speed (somewhere around 30 degrees before TDC) while still retarding to about 5 degrees before TDC for starting and idling.
