O.K. guys, thanks for u r response, but I am not familiar with all the jargon that you used to describe the above ignition E.G "dizzy" etc. I'm a rooky!
Anyway,here is the situation in it's entirety;
I have an old 13-B in my Triumph TR-7, I think it is about a '74 and maybe from a pick-up. It has a carb and no turbo.
It is running poorly at present (missing, studdering, etc). Adjusting the carb mixture didn't seem to help so , I thought I would take a look at adjusting the points.
After removing the twin distributor cap, I find that there are no conventional, adjustable points there, and concluded that this was a breaker-less system of some sort.
Seeing this made me wonder if the previous owner had changed out the conventional points to something more modern? If so, I need to know what car and year they are from.
That's why I asked the question: "When did the 13-B switch over from normal points" to this system........so I could read up on them, and determine how to adjust them .
Any help appreciated!
