I am having a problem with an old EECO brass valves. The elevator when traveling up takes off good but stops very hard. In the down direction it takes off hard but levels and stops very well. I do not have any information and never adjusted these valves before, does anyone have any experience adjusting these valves or possibly a default settings. These are brass valves with two separate down valves, the up and up leveling valves on the same body. Thanks for your help in advance.
