NS is right:agree: But some foundational reasoning is: The fuel will "Clabber" without the stabilizer. The water that IS in the gas, will assist it in clabbering. So, after adding STABIL, then run it a bit, to get the stabil into the carbs. and fuel sys. IF you do what you said, then you still will have partially clabbered gas.
Clabber is what non homogenized milk does, when left out for 3 days. It separates solids, and whey. When this occurs in the carbs, the solids attach themselves to the inside parts, and the whey evaporates.
