If enough water collects in the tank, it can get drawn into the engine, where it can cause the engine to run poorly. Ethanol acts as a solvent in older engines and can dissolve old gum and varnish deposits from the gas tank and fuel lines. These deposits can then clog the very small orifices in the carburetor.
