I fitted this standard Lumenition Optronic Ignition system to eliminate the points from the Sugga's Bosch distributor. I used the standard Optronic system because it can run with the Sugga's original 3 ohm coil. If the Performance Optronic system is used then the coil would need to be changed for a matching high performance low resistance 1.5 ohm coil. On such a low-revving engine this Performance constant energy ignition system is totally unnecessary, so don't bother with it. All the screw caps on the original coil should be unscrewed and the connections inside the coil should be cleaned of any dried grease or corrosion as this can cause a high resistance reading for the coil (ie anything above 3 ohms) and reduce the intensity of the ignition module's spark. These screw caps can be difficult to remove so you may need to heat them up and get penetrating heat in to their threads, whilst rocking them back and forth with molegrips. Don't grip the screw caps too tight as they are quite soft. The Optronic system uses an infrared optical eye to trigger the ignition unit via a 6-bladed chopper. I bought the ignition module and infra-red trigger secondhand but I had to buy the chopper and base plate directly from the manufacturer, Autocar Limited. Their technical department advised me on the best parts to use as the Sugga's Bosch distributor isn't listed in their catalogue so they supplied the closest fitting items, which went in perfectly. I had to replace the original base ...
