Answering this one question will help narrow it down.
 With the engine running at speed hold the pump rack from moving with your finger. Then does the RPM remain steady?

You can't slow it down by moving the rack?

There is perhaps too much slack in the linkage, permitting the fuel rack to wander.  I fixed this issue by drilling a SMALL hole through the end of the fuel rack, on the filter side of the fuel rack.  Placed a SMALL hook-spring through the hole, and fastened it around the filter.  That small spring took up that slack, and prevented the rack from wandering.  Eliminated my rpm wander entirely.  PM me if you'd like pictures.
