No ordinance or any item or part thereof shall take effect without the mayor's approval, unless the mayor fails to return an ordinance to the council within ten days after it has been presented to him, or unless council upon reconsideration thereof on or after the third day following its return by the mayor shall by a vote of two-thirds of the members resolve to override the mayor's veto.

(b) The mayor may attend meetings of council and may take part in discussions of council but shall have no vote except in the case of a tie on the question of filling a vacancy in the council, in which case he may cast the deciding vote.
