Control valve adjustment

my remote hydraulics are always going up or down. If for instance, I have my disc mower on I have to keep the handle rocked back to keep it on the ground, or forward to keep it lifted. If you return to the middle detent it goes the opposite way. Can this be adjusted or does it have a internal leak? It does have 2 studs in the back of the valve with lock nuts that appear to be adjustable. It's a JD2130 by the way. I assume this is not normal operation anyway, it does have 3 detents, but there is no neutral position anywhere in the levers travel.
 

There are 2 different styles of scv's that were options on a 2130. One is poppet style that can be repaired or adjusted. The other is a spool style valve that requires replacement as no individual parts were ever available.
Here's the complete poppet valves part #s and they're not cheap.
