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

How is it all wrong? It's a 750. There's nothing wrong with the carb as far as size is concerned. Someday, we are going to leave all the goofball old wives tales in the ditch where they belong.
It's a little big but the big issue is he said it is a stock engine with a 750 double pumper. That is wrong IMO. I have tuned carbs for over 35 yrs. and can make a double pumper run ok on a stock 360 but find a vacuum sec carb is much better matched to a stock engine.
