I have a good set of the 1979 DOHC Limited carbs that have been cleaned, not ultrasonic, in good shape. Over jetted for 4 to 2 exhaust, everything else stock. Sea level. Jets, bowl gaskets, plugs, mixture screw O-rings, float needles replaced. Have not split them for the air cut off diaphragm replacement. Seem to have sort of a high idle when coming off throttle. Comes back down to proper RPM sitting still. Does anybody know what gives, and how to possibly fix? Thanks.
