New Clutch.....Problems

it's been many, many years since I've been into a 4spd, but I kinda remember there being two positions for the fulcrum of the throw out arm. As i recall, the fulcrum is bolted into the back of the bell housing, and there are two set of holes. I might be conflating another app, so I'm not positive, but it might be worth taking a look when you're back in there.
I agree with the previous poster to take this opportunity to take a close look at your clutch linkage. Make sure everything is in place and in good working order. The geometry is important. You want the zbar perpendicular to engine centerline. You want the arcs of the arms to be centered in their travel.
