basic regulating question

There should no space between the top of the jack and the hammer but. You eliminate this space by adjusting the capstans. The adjustment should be so that when the hammer rest rail is pulled back, there should be just the slightest movement back of the hammer. But the hammer should move forward when you push the hammer rest rail forward. If the hammer rest rail doesn't move, you can still check for proper adjustment by barely touching the key, and watching the catcher. It should move almost instantaneously.

Greetings,

?

?????????? This may seem like a dumb question but after?I level the keys and insure even key dip in an upright, why dont all the jacks have the same distance between the jack tip and the hammer butt after?I depress the key and hold it there? Are my capstans uneven??Maybe its been too long a time since I learned this, and having only done about 4 regulations, maybe I am not remembering something.
