1. A packer setting mechanism, comprising:
a setting chamber housing positionable about a mandrel to define at least a portion of a setting chamber between the mandrel and the setting chamber housing;
a setting port fluidically coupling a through bore of the mandrel with the setting chamber;
a valve element biased toward a closed position within the setting port; and
a guide sleeve disposed about the mandrel in a first position that props the valve element to an open position, the guide sleeve moveable to a second position in response to a threshold pressure applied to the setting chamber that releases the valve element to the closed position.
