Use or don't use vacuum advance on distributor???????????????????

Douche Bag? Really? Go buy your lean burn distributor, I'm sure your car will run perfect.
All the lean burn one is is a mechanical distributer. I and others have asked you questions and to elaborate and you won't and then get a attitude basically calling me stupid for trying to learn. If that isn't be a d bag and a know it all I don't know what is.
