...Your Vacuum Advance should be connected to a 'Manifold' Vacuum source! Continuous at idle, but decreases slightly when the throttle is cracked and opened further. The way You have It connected now, to 'Ported' Vacuum; the 'Initial' is already set, But as You crack the Throttle the 'Port' Vacuum Increases, the Vacuum Advance Increases, as the RPM rises the 'Centrifical' Advance Increases; ALL added together It is Too Much advance at Cruising speed and above!...
