Quoting Removed, click Modern View to seeThe fact that it goes down very quickly when engine is turned off could mean that control valve is in the 'dump' position (perhaps a linkage adjustment problem). It could also mean that there is a leak at lift cylinder or in oil path to same. Other possibilities are that backpressure valve is not relieving, thus keeping high pressure applied at all times & under these conditions, IF the dump path flows less than supply path the lift would rise regardless of control position............this is why I asked about weight being lifted (under such circumstances it might lift something, but not 900#). Some people can tell by sound of pump & sound of engine load, whether or not the pump is working hard (high pressure) all the time or only some of the time. It should be only some of the time.....another indication of backpressure not relieving. Unloader valve stuck in raising position would act same as backpressure not relieving. Eventually you will have to take apart & verify that all valves are free to move, correctly installed, and linkage is set correctly.
