The author modifies the calculation of the QCD correction factors in the {delta}S = 2 effective Lagrangian for K{sup 0} {minus} {bar K}{sup 0} mixing to allow top quark masses in the range 50 GeV to 200 GeV. The author gives constraints on the top mass and Kobayashi-Maskawa phase, determined from the measured K{sup 0} {minus} {bar K}{sup 0} mixing parameter {epsilon}, and find that the factor B{sub K} and the ratio {vert bar}V{sub ub}/V{sub cb}{vert bar}cannot both be small if m{sub t} {lt} 200 GeV.
