OK, I looked at the series of photos on Jack’s site. It looks like there is a coil with condenser mounted where the magneto should be. I can’t tell whether is is a buzz coil or not.
In back of the drum that normally drives the mag, there appears to be a fiber disk, likely with a pin in it that grounds out to the mag drive shaft. Next to that, mounted with an adjustment handle, must be an isolated point, likely spring loaded. As the disk spins, the pin lines up and contacts the isolated point, making the circuit to fire the coil. The isolated point is mounted so that there is some timing adjustment using the handle.
