Buds53,
As others have mentioned, there may already be a cable hole in that throttle rod connector. Should be easy enough to disconnect the clip, pull the rod connector back from the carb and see if it's there.
If no hole, the connector can be removed form the rod and one drilled towards the outer end of the pivot post. Just make sure the drilled new hole is parallel to the existing rod hole as the cable needs to "pull" straight up in alignment with the rod movement so it doesn't bind.
Let us know what you find.
