<VV> Vacuum Advance? Re: custom distributor curve?

[BobHelt at aol.com]

This doesn't sound right. The VA simply removes the spark advance that IT  
PROVIDED when the throttle is opened significantly. To call this a retard is 
a  play on words as I see it. It is still correctly called a vacuum advance 
 unit.

Has  anyone yet realized the term 'vacuum advance' is a misnomer?  In fact, 
 that thing with the vacuum line that is hanging on the side of the 
distributor  momentarily RETARDS the timing when the throttle is opened to give the 
extra  fuel from the accelerator pump time to get to the  cylinders.
