Neither of the ones I have run is very snappy. Takes keeping them revved up to get them to perform adequately. No spinning a wheel unless its muddy. That is mostly a 944 and a little bit with a 59a 922b. Steering went out on the 922 not long after we got it going.
There is a suction strainer that will be plugged with clutch material if there is a major failure.
Make sure there is a cab on it or the plug that covers the center of the steering column is in place so water cannot go down the hollow column and get into the stearing gearbox.
My 922A is not what I would call snappy either. It will however fill the bucket with pit run digging into a bank. It will not spin the wheels in gravel either.
At the risk of asking the obvious, did you run it long enough to get the trans up to operating temp?. They can be a bit of a slug until the oil warms up, but after that it should respond well.
