Does your carb have a hot idle compensator? It will cause the idle to raise if stuck open.
Take the throttle body off and hold up to alight to check the throttle plate seal against the bore of the throttles. The screws in the shafts have to be tightened with the throttle held closed to force the plates to orient themselves to each bore.
