Why does the choke help an engine start when it is cold? I know that the choke restricts the air flow and thus makes the mixture of air/gas entering the engine more concentrated with fuel, but why would that make it easier for the engine to start on a cold day? Shouldn't the engine be easiest to start when you send in the ideal mixture of air and gas (since combustion needs both) and not when you send in a extra-concentrated mixture of gas?
