Um,I'm having the same issue (albeit, 1000 rpm in N), but my throttle lever isn't even contacting the throttle stop. I can twist it barely to make it touch, but it snaps back to a millimeter or two above the stop. I've traced it to the vacuum plunger thing on the front of the TB under the black cover (it kicks out, or *assists* the throttle lever when revving it looks like) - it's resting position is keeping the throttle from closing completely. Anyone have any experience with this? It has a vac line going dtraight to the TB, with black plastic spiral wrap on it.
