I'm thinking may be vacuum leak, but increasing RPMs usually signal a vacuum leak, correct? Did not have chance to spray carb cleaner, etc. around manifold surface and carb gaskets. Butterflies are fully closed in outer carbs, linkage is set, 2 turns out on idle screws on center, 1 turn out on idle set screw (from "square transfer slot setting" in the "unofficial six pack tuning guide on Moparts). Thoughts? '71 SSP - SOLD!
