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

Thank you. I don't remember being rude or anything I asked a simple question because I am trying to learn and this guy is being a d bag. My first question was how to tune the motor to work with manifold vacuum because hooked up the car sounds like crap compared to not hooked up. I do realize I am working on the carb as well but I feel I am battling two problems.
Douche Bag? Really? Go buy your lean burn distributor, I'm sure your car will run perfect.
