Replacing all the springs fixed the problem with the pump control rod being 'out of time' on my H. The hold up ball springs were both short. One was 3/16" shorter than the other. The valve cam and piston lever spring had a cracked leg (it is a hair pin type spring with several coils).
The free length of the Hold up ball springs (pn 15056E) are 1.125". The Locking clip spring (pn 15257E) is 1.525" long. The pressure relief valve spring (pn 15258E) is 1.90" long. The arms on the Valve cam and piston lever spring (pn 15068EB) are bent back 3/8".
This spring (15068EB) has several coils and at each end, instead of a hook or a flattened coil, there is an arm that extends tangential to the coils (see the illistration in the parts book). If you put a straight edge along the back of one arm, the end of the other arm, at the back of the arm is 3/8" below the edge of the ruler.
