Thanks for your technical input which will help us refine the job. Ron made up the trial Capacitor Discharge Unit shown in the photos using items from his shed. The engine pictured runs well with the unit and ticks over very slowly when idling. However, the spark is not impressive.
You can identify the main items: the coil is from I think a Suffolk 4 stroke with 3 leads from the coil, the condenser [capacitor] is a .22uf normally used in small engines and also a diode [rectifier].
These 3 items are wired up as in the diagram and connected to the original 3 leads coming from the flywheel unit: feed coil, points and earth.
The next step is to assemble a tidy looking unit contained in a plastic box.
