What system did you use ?Easiest way is to pop the distributor cap off and see if you have a set of points in there. if you pull the cap off and see nothing that resembles points (maybe a plastic looking block) then you are already electronic. That is unless you can see a module with wires coming off of the side of the distributor, or wires going to a separate ignition module before you get the cap off. 1 wire you have points, two wires electronic.
I made the switch from points to electronic but I'm about to change back. I've had more random misfires with the electronic ignition. I personally feel a well maintained set of points are preferable. Can't say I've noticed any difference in efficiency or starting either.
My advice would be to refit the original Lucas unit and fit Lumenition - the full Optronic kit,not the cheaper version.Its expensive,but totally reliable and way better than points will ever be.Genuine rotor arms,dist caps and leads are also a must too...I bought a complete Accuspark distributor and coil, but I'm really not impressed with it to be honest.
You had all the bad ones then,I've been fitting them and using them for 30 years and never had a problem.My brother is currently 1/2 way around Oz in a 67 SIIa 6cyl - on Lumenition.My other brother has a 1933 Austin 12/6 on it,runs like a sewing machine.I had the optronic on my landy, I bought it new and it lasted 3 months and the main box died. That was replace under guarantee and then it lasted until it was out of guarantee and it died again. This time it went in the bin and I've never bothered with luminition since.
Thanks for the advise , I shall just give it a tune up and see how it goes , ,lineage wise I expect no more than 1000 a year. Only done 100 since I had it and it's was 30 miles away when I picked it up. Any one tried LPG ?!
On the question of points v electronic, if you have points make sure you have the knowledge and kit to clean and adjust them, and carry a spare set of contacts and condenser.
