Reply to "Delay Mechanical Ignition advance"

4V & Proud thanks for your question. Vacuum advance is present and actually has no impact on the problem. I tried with and without. The Vacuum advance is only a factor when the throttle Blades are near closed (i.e. cruising with Manifold vacuum deeper than 15 In/hg) and is completely neutral under acceleration were the Vacuum is much less and potentially near zero. Vacuum advance is hooked up to the ported vacuum port on my Holley doublepumper.
