The seat rides stiff, no movement even when in the soft ride postion. All linkage is connected. Even removed it from the valve body just to see what it looks like in there. when removed the oil blew out and the seat fell to bottom. Everything appears normal, looks like its just supposed to direct oil flow.. Haven't taken the valve under the seat apart as it adjusts seat height not ride comfort. Put a brand new accumulator on, did not help, yes it is charged, double checked. Seat height up and down functions normally.
