Well its all done and working great. For my first time on this it was better than I thought going in. Did not have and satisfaction on using the dial indicator like the book said. The screw heads were just so uneven. Even filed them smooth but probably crooked. Instead I used long strips of brass shim stock in .001 and .003 size. Laid them carefully over the valves and reassembled. Adjusted the screws till they lightly touched, locked the screws and pulled out the shim stock. Reassembled tractor and it works perfectly. It must of been messed up for a while cause it never worked this fast before. Response is fast. Well at least in comparison.
