When the car has the high idle problem,  try pushing the throttle butterflies
closed right at the throttle itself.  If than cannot make the idle go down,
the problem is almost certainly in the carbs themselves, not further upstream in
the linkages.

You should work on the throttle mechanisms starting at the carbs and working 
upstream,
making sure everything works smoothly and is properly adjusted.  For example,
there is supposed to be clearance in the linkages where the throttle shafts are
actually driven, to ensure that the idle speed does not get affected by small 
changes in the
rest of the linkages.
