I am still trying to get my head all around timing and you seem to have a far better understanding of all the science behind it which has been an great read. I have a timing light and a timing tool and I feel like I am going to start using the light more for my bikes as the tool does what you mentioned and make it impossible to see and adjust things when you have it set. The light will require lines on my flywheel which gives me the position I am getting spark at. I can then use a degree wheel to find where the points should be opening and mark that as well. That will allow me to rotate the flywheel to get where I need to make the adjustment and then can fire up and test the change with the timing light.
The feeler type tool that I have is good for finding some measurements but I am finding it harder to set an accurate timing with these days.
Is this sounding correct?
Also I seem to be lost on which direction I would move my stator to advance/retard timing. I feel like it is this. Let's say the flywheel rotates in a clockwise direction. I would rotate the stator counter clockwise to advance the timing and clockwise to restart the timing?
