"After running the engine and warmed up, turn off and look down the carburetor to see if gas is dribbling from the venturi. If so, then the discharge check ball may be leaking, or a non vented gas cap is being used, or perhaps the fuel bowl vent is plugged off."
Seem unlikely that for both of your carbs the check ball or vents are bad, so boiling the alchohol in E10 gas is probably the cause. Your better experience with non-alchohol gas seems to confirm that. But sometimes E10 gas is all we can get.

Maybe check your float levels to the low side of the spec?
Maybe drop thermostats from 180 to 160 degrees?

Maybe put a phenolic spacer under the carbs to block heat transfer?
