In this case, 2.09 mm would be down the side of the bores ? Or from the centre of the bores? It makes quite a difference no?
thanks

Is the problem that you aren't using a dial indicator?? By your description it sounds like you are simply trying to determine the 2.09mm distance by sticking a ruler in there.. That in itself would be fraught with problems and nearly impossible to accurately determine. You need to try and approach it as the other guys have said, by using the dial to find TDC. If you buy that LCR windmill that goes behind the points plate, timing becomes much easier. Hope you get it sorted out.
I have a boyer brandson ignition. The timing is non adjustable for individual cylinders. I'm going to time it off the center cylinder and adjust as needed from there. I wish I had a more adjustable ignition system but it has to be better than points!
