rightly or wrongly, every seven I've had I've timed quite simply without worrying about angles. This goes for a bog standard early coil with L/C head to a breathed on special with a lairy cam, big valves and H/C head.
Find No1 compression stroke.
Lign the timing mark up with the oil pressure take off.
Fit the dizzy and adjust so that the points are open with the rotor pointing No1, and the heel of the points are smack in the middle of the square on the dizzy cam.
I will guarantee that it will start and run. I fine tune by feel/ear. It is unusual that I have to take the dizzy out again. Usually there is more than enough range.
