I have managed to eliminate the crawl on the second stage of the trigger and as they say, it breaks like glass.
I have use a torx tool and turned the screw clockwise roughly 1 turn. Note you have to strip the stock form the rifle part, the second stage screw is hidden away. It is not the big screw behind the trigger, that would be your first stage setting screw.
Question however, is it possible to adjust the (weight of the trigger pull) on the HW97K. I do not want it to lite (100g or so) but a bit lighter than what it is now would help a lot.
Should the second stage setting screw be adjusted even further?
