Hello! Ive got an HEI distributor giving me trouble. Ive got the stiffest springs in i could find, but its giving me over half the mechanical advance at idle. I know this because i took out the weights and got 2 degrees initial at idle. I then put the weights back in and got 20 initial, 29 total. This is all with the vacuum disconnected of course. I tried grinding my weights to make them lighter even, and ive cleaned all the surfaces. Any ideas?
