tpmx, What I am about to write is somewhat generic because I'm not sure what your valve has but here goes.

The spring and poppet you talk about in the spool may be what is called a regeneration valve and the purpose is to refill the upper end of the lift cylinders when the boom is dropped rapidly. Not sure how it may apply to your problem.

Many hyd valves have what is referred to as port reliefs or circuit reliefs for each operation. It would be common for hoist up to have one to protect the cyls and boom if when up something fell from above or a bank would cave in. If this relief was bad or had a broken spring it would cause your problem and would not effect the down operation.

Another thing, is it possible that the linkage is worn to the point that the lever is hitting the frame work before the spool is stroked enough? I have seen this before.

I doubt cylinders if you have down pressure but they could be tested for bypassing.

As I said these are generic comments and may not apply to your specific valve.

Good luck, I'm sure you will get it figured out.

Dennis
