Thanks Guys.
I have 8* initial and testing showed that the centrifugal advance is only advancing 10-12*. I think the springs are so stiff they aren't letting the weights fully advance. Weight advance seems to start after 700 rpm but doesn't advance past 20-22* and stops advancing before 2000rpm. I noticed a shiny spot on one of the weights, it looked like it was rubbing on one of the ribs on the underside of the rotor so I mildly clearanced that rib. I retested and it showed no improvement. I did test the weights by hand and they are smooth. Looks like I do have room for improvement.
