so i took the haynes advise as how to set static timing by means of a test lamp
and prepared my setup using a 12volt test lamp
it worked very well
set your engine at OT as previous pictures shown, slacken the clamp bolt so you can rotate the dizzy, first you turn the dizzy clockwise far enough so you are sure that points are closed, then you switch the ignition on and then very slowly turn the dizzy anti-clockwise until light is on, and there fix the clamp bolt
you get a couple of extra checks using this trick, first is you have light so you are sure that there is electricity going on there, second, you will hear a loud click as the HT lead produces an arc, that means that your coil is working
you can see that this job meant that i just turned the dizzy body clockwise an equivalent to those 5mm, which meant effectively putting the mark in the middle
put everything in its place again, and then the engine started like a champ
amazing, problem solved
