FEL not curling down properly

[oakhilltop]

I have a JD 2305 with a 200CX front end loader. Recently, when I attempt to curl the bucket down to dump a load, the FEL curls upwards. I can get it to curl down if I do not push the joystick fully to the right. But it goes much slower and if I push it too far it curls upward and I have to start over. Does anyone know what the cause of this could be? My guess is that there is some vale that controls which hose the fluid goes to and that valve is deteriorating. The tractor and FEL were purchased in 2009 and has the optional valve that allows switching between the FEL and the mowing deck. I have not used that valve for a few years because I've been mowing with another piece of equipment

Does it have regen on Curl/dump? Maybe the regen function is acting up. Post in the Hydraulics subforum where it will get more direct attention.
