Bj42 Clutch Problems

I have a 1981 BJ42 and a couple months ago I replaced the clutch slave cylinder all has being well untill today, When i release the clutch pedal it dosn't seem to come all the up, like before when i was losing fluid through the faulty slave cylinder, I checked for leaks and i have lost no fluid. I love my truck but every time i replace or fix something, something else allways seems to happen, I guess this is part of the attraction.

I am not full sure on this, but here goes.
I reckon it is either a missing return spring on the clutch or the Master Cylinder is RS again.
