lokar kick down adjustment

QUESTION: as I also have a lokar kickdown, currently where I have it set at is there is no tension on the kickdown cable at idle, and there is slack on the tranny kickdown lever. during throttle, it pulls the cable/ lever at the tranny at the same time so it doesnt really kickdown when ya step on it....must I tighten it at the carb like you say? will there always be a constant "pull" on the trans lever if the cable is tightened?
