If you did not do it yet, try pulling and compressing them several times in a row. That may get them feeling more consistent. When they sit for a while the oil has not had a chance to work through the circuit.
they are supposed to be worked anyway. if I remember right, turn them opposite of being installed (upside down) and fully extend and compress them till there is no slack spots in them. ----old Chrysler mech. told me that.
