It is better that the ethanol absorb the water and take it through the carb and out of the motor. The alternative is the water sits in the bottom of the tank and/or float chamber and rots it out. Here in north central Alberta where we can get some ferocious cold spells we add a LITTLE methyl hydrate to the gas to absorb the water and flush it out before it freezes and stops the gas flow. Use of ethanol laced gas negates this, although the excessive quantity of ethanol used causes many other problems.
