I have found that, even with two heavy silver springs in it, my MSD Billet dizzy has all mech advance in by 2600, which is too early - I was aiming for 3000 rpm.

Anyone else had this problem or know the cure? I guess even heavier springs might be the answer but don't know where to go to get the right weight.
In any case, this is a long way off the MSD published advance curve for these springs.
