[QUOTE="Simon Dinsdale, post: 25704, member: 58"] Tracey, Go points / coil ignition. That is what I use except mine is a home made unit. Uses a pair of Ford points which are identical but mirror image. Each points on a seperate slotted carrier so the timing of each cylinder can be set seperate and two condensors and coils so each cylinder is totally seperate apart from the battery and ignition switch. Timing advance is done by an original magneto ATD in the timing cover. Only problem I have had is the occasional condensor failing approx once every 5 years. Spare condensors are easy to carry and take 5 minutes to replace. In fact on mine the condensors are now mounted under the mag cowel on a bracket with a spare also mounted so it is just swap the connector over if needed. I also use two small Triumph / Norton coils (or could use a twin output coil) so you can also get rid of the distributor cap and rotor. I tried the modern electronic method and it failed at a rally. That was the only time I have had to be relayed home due to ignition. Never again. Reliability and the ability to fix on the roadside if required is everything in my opinion. If an electronic system fails then you are stuck and if you follow the forum then you will see that a lot of people are having failures on electronic ignition across a lot of the different systems. Alright points / mechanical timing are crude, but they work, and lets admit the engines are an old slow reving design that don't really need the technical timing advantages a modern engine needs to pass the modern emmissions / legistation. Hat on awating the flack. Simon [/QUOTE]
