Disclosed systems provide cost effective dispensers of construction sealant, sausage tubes and other products having varied and even unknown levels of viscosity. A variable ratio drive cam pivots in response to the trigger tension caused by the viscosity of the material to be dispensed. In a relative high force mode, encountered with high viscosity payloads, the drive cam slightly pivots, keeping the distance traveled by the drive rod relatively small in response to a pull of the trigger. This results in a relatively high thrust ratio.
