I've been confronted with a similar situation and my solution was to set the timing a bit retarded so that it was right when advanced. It was trial and error. I'd set it and then take it out and try to make it ping. If it did so too easily, I'd come back, retard it a bit more and try again. Once I was happy with it, I left it alone for years. The motor spend by far most of its time running with the timing advanced. Idle was tyical of a retarded engine but it wasn't hard to live with.
