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?

George,
Float drop is done by bending the little tang at the back of the float. This little piece touches the needle/seat and how much you bend it decides on how much that flat will drop. If you want a pick, I can get one for you. Make sure these settings are correct BEFORE getting into electronic ignition. Not knocking FBO stuff, but why spend money if you don't need to?
If you say your timing is at about 8* or so BTDC, the electronic ignition is not going to solve the surge and backfire issue. That I believe is in the carb. I had the same thing on a car here iwth MSD. under light acceleration it would be fine, but ubder heavy acceleration it would pop, stutter, backfire. THe floats were WAY off. Once reset, car ran great.
