On checking my mechanical advance with my dial back timing light it showed only 10 degrees of mechanical advance. The dizzy is a GM HEI with a MSD 6AL. A call to MSD Tech told me that the light will not work with the MSD system. So muggings here went and bought an MSD light. Yes you are ahead of me I think, you guessed it, this light gave exactly the same readings!
So the problem is, when I check the weights by hand, there is plenty of movement. Then I put the cap on, start the motor and all I get is 10 degrees of mechanical. I've tried all the springs in all the colours and obviously all that does is change the commencement of the advance.
Any ideas Guys as I have run out of them and the patience is getting a tad low too!!
