Stupid Distributor Questions

Redfast,
I will look in the service manual tonight after work, but if these procedures are not in the manual, I'm afraid I will not understand how to adjust the drop. I know what needs to be "adjusted" to change the float level, but not what to do for float drop. Thanks for the explaination.

3404speedvaliant,
I played around with a spare vacuum advance can I have using my vacuum pump and it seems to me that the allen adjustment screw didn't change the amount of vacuum advance, it seemed to change the amount of vacuum required to get it to move. Am I wrong?
