An improved plunger mechanism apparatus has a manually adjustable bypass valve to increase well flow production levels in high liquid wells. The plunger's descent rate can be fine tuned in the field by adjusting the orifice opening so that liquid can optimally flow through the plunger core during descent. Efficiency of well flow is increased by the addition of a variable bypass orifice, which can be preset in numerous positions to vary the amount of liquid bypass allowed depending on the well loading parameters. The plunger mechanism of the present invention allows numerous bypass set positions, which can be tuned at a well site and later changed as a function of future well loading parametric changes.
