Hi, Danny. You need to remove the action from the stock to access the sear engagement adjustment screw. It's a small torx screw in the front of the trigger assembly. IIRC turn it clockwise to decrease 2nd stage creep.
The right side of the pivot is a lock nut, so loosen that first, then you can adjust the tension with the left side.
I've had a few HWs that needed the sear adjusted. My new 50 didn't need that, but it did have a tight pivot. The locknut was so tight, I had lay all my weight into it to break it loose. I hadn't had that issue other HWs.
Good luck with yours!
