Carburator size

I hope this doesn't post twice. I thought I sent a similar post to below earlier but don't see it.
Rusty, I’m going to show my ignorance here with regards to carburetors. I’m not questioning your thoughts, I’m trying to understand and learn from your experience. I fully understand what happens to gas when left to sit, especially with the crap they are selling us now and calling it gas. What I don’t understand is, if there are two bowls, what difference does one or two inlets make. If the secondaries are vacuum operated you are still going to have to use the right foot vigorously once in a while to replenish the supply with fresh gas. Now if it was manual secondaries I could understand it. Thanks for taking the time to educate me. I may be slow but I am trainable.
