[FC] vacuum advance question

[aircooled6 at prodigy.net]

I had that symptom on a "rebuilt" distributor.  As Bob Helt has  
already mentioned--the advance weights under the points plate are in  
backwards which causes them to do the opposite of what they are  
supposed to do.   If you have another distributor, youll be able to  
see the difference when you open them up.  Move the weights to the  
opposite sides, reinstall the springs and it should work properly.
