X1100C Dump Bed Hydraulic Question

I recently repurposed the dump bed hydraulic circuit to operate the angle feature on my snow plow. I control the angle from the dump bed lever but it is jumpy and a little too sensitive. Can someone tell me if the system has a built in flow restrictor to adjust the fluid flow rate for this circut? I know I can install two line throttle valves but before i invest in these I would like to know if there is any ajustment in the machine itself I could look at.
Thanks
