You want to adjust the cable so there is very little/almost no play in the cable. There are usually nuts on a threaded post at the end of the cable housing. Back the nuts off slightly, then adjust the posts out until the slack is gone, then tighten the nuts with the posts in that position. You might need to use a pair of pliers or wrench to hold things in place depending on your adjustment mechanism. Test the clutch again.
