The curl spool is part of the joystick valve. (assuming that is what you have).
The spool is what directs the fluid to the ports, then hoses, and out to do work.
A joystick valve has TWO spools, because it is designed to control TWO functions. One spool does lift, the other does curl.
So if curl dont work, but you put the curl hoses on the ports for lift and now they work....that tells you that everything from there out to the bucket is fine. Problem is AT the valve, or the connections at the valve, or internal reliefs/cushions IN the valve.
