Removing confusion when giving instructions is often a challenge.

Even when we understand perfectly well what we are trying to say, writing so that it can be clearly understood by the reader can get away from us.

When the instruction says up or down, what is being moved up or down? Is it the screw that holds the index plate? Or, the index mark on the case? Or the marks themselves?

The correct reference is very important.

Clint, you have asked a simple question, but it's hard to tell how much information you really need. Help us out with a few more details ... distributor on the engine or not, running or not ... have you ever replaced points in a '34 helmet distributor (if that is what is installed).

The guys will help but need to better know what you are trying to do.
