The thing is, there is science behind that theory. The colder air is the denser it is. The denser air is the more Oxygen is present.
I don't know whether it's true but there is the idea that if the fuel air mix is too cold that the fuel drops out of the ideal droplet size range for atomisation. This could completely be nonsense though.
