Confidence boosted a slightly longer run, again on a very hot day and in heavy traffic and the same problem I had expeirenced in Wales, only more often. When I came to a standstill in the traffic, if I didn't immediately put her into neutral the engine would die, she would restart immediately, but it was a bit disconcerting to say the least.
I had done a lot of research on electronic ignition systems and to my mind the Pertronix Ignitor came out on top with relaibility and simplicity of installation. I was pretty sure the problem was point related as it must have been at least a couple of years since the points had been adjusted whilst under previous ownership. I hadn't adjusted points for probably 40 years I didn't want to start now and Pertronix Europe got a system to me the next day and it was fitted in an hour or so.
The rotor was also firmly pushed into place and dizzy cap replaced and wiring connected, the only slight complication being that I had to run a fresh, ignition switch controlled, 12 volt suppy to the ignitor, as the original set up only supplies 6 volts to the coil and distributer, too long to explain, but I understand why that is. Stella started immediately and I went for a run to check it out and all was fine. I noticed on return that the dizzy cap was wriggling about and that shouldn't be. When I removed the cap I realised that the carbon brush had been pushed right up into it's housing, the nose of which was rubbing directly onto the rotor, which was why the cap was jiggling about.
I resolved this problem by grinding a few mm from the underside of the rotor as I realised that the magnet sleeve had raised the rotor by 2 mm.
However, as I couldn't get the carbon brush to come out of the housing, I assume that it had been worn right down, but again Robsport to the rescue and a new dizzy cap arrived the next day and now Stella appears to be once again extremely reliable with a very steady tickover. Another job ticked off.
