Hein Werner 2-ton 93642 rebuild question

[wkeene]

I'm rebuilding my jack and have a question I cannot find an answer to. In the valve with the smallest size ball that's held by a plunger cup (name?), heavy spring, and a screw/plug under the welch plug, how tight, or how far down, should that screw be? I probably should have counted turns when I pulled it all apart, right? I'm wondering about the part circled in red, in case my description is way too hard to follow.
Thanks

You need to find a place that has a testing rig. See the last page of the attached article. You could start with 3.5-4 turns back and see if it lifts a side of a car. Tighting a quarter turn at a time to test it lifting a lighter car side under the max jack weight Capacity. Without the calibration test rig, you risk bending the jack and worst.

I was thinking of doing a similar process. Most of the work I do is with MGs and the biggest thing it lifts is my GMC 2500HD so I'm not overly worried about overloading the frame.
