I have combined 2 SK single action arms in order to attempt to make a double action Provid arm and I am running into some questions. One of the arm sections seems to be tuned differently than the other so it is bottoming out when the other is horizontal. The trimming knobs aren't making a large enough adjustment to correct it and they were set the same on both sections anyway, so that's not a viable solution. Can anyone tell me how to tune these arms? It seems like I should turn the screw in the photo attached, but I didn't want to attempt that before asking the experts.
I also want to upgrade to socket block at some point.
Any advice would be appreciated.
