In my newbie opinion if corn base fuel sits in a hot carburetor (after a drive) the fuel may turn to vapor more easier than 100 gasoline. I think though with cool fuel from the cowl tank flowing in the the bowl that's not likely to happen... But once you turn the car off and let it sit... you might in theory experience this... Tests and experiments could likely proves this once and for all... I might take a carburetor with a small port-hole on the side of the bowl and a camera to really prove or disprove...
