Huff, I have a 123 - the one with the 16 settings per small screwdriver, dizzy out. I have attached the test data from the Jaguar Series 1 Workshop Manual, the curve maps (such as they are, from little 123 book) for the 123 and my graph representing how a couple of the 123 curves overlay the Lucas test data, per manual. IIRC my car is on curve #2. The kneepoints on the 123 are not as pronounced as the mechanical weight “changeover”
would have it on the old dizzy. Hope this helps a bit - expect you will have to fit up your own dizzy curve as your car is later than mine. Regards, Paul:blush:
