I just relpaced the motor an put a new hose on the lift.
I would say you have a bad valve in the power unit. I am guessing the valve that you are adjusting is just what you said controls the drop speed. When you crank it down it wouldn't allow fluid back to the valve on the power unit. Not sure what you have for power unit but most of them have valves that open and close so it would open and provide fluid to lift the ram and close when you let off the switch. So if you had a bad O-rings on the valve it would allow fluid to return to the tank and plow to bleed down. Might post a couple of pictures of the power unit
