Strictly personal, when you ask about the idle vacuum, I assume that you mean the intake manifold vacuum at idle. Yes? I haven't measured that, but should be 18 mm Hg, I think, but I can check. Your idea of a slipping damper or some odd ball deal with the timing (where it would like right on the gun, but be wrong for another reason) is scary, but as you said, very unusual. thanx steve
