Evaporating Fuel in Carter 4-Barrel Carb?

I have exactly the same issue in my Valiant and Barracuda. Carter 1 bbl and Carter 625 AFB respectively. I understand today's gas formulation makes it evaporate quicker than before. Seems to me 24 hrs is the limit. If I drive either car on consecutive days, it's not really a problem. I don't mind the extra cranking because maybe the oil starts moving and gets where it needs to be before it fires.

I wonder about that sometimes, because my motor fires right off as soon as I turn the key.
Probably a little better for the motor if oil gets there before it fires up, but if it worried me that much I would either get an oil accumulator or just a switch to kill the ignition till pressure came up.

Then again, they pretty much all fire right up without pressure first. :D
It just relies on residual oil from last time it was running until it does.
