We examine effects of final state interactions (FSI) in kaon decays using anew scheme without the Omnes function, and show that while Delta I=1/2 rule isimpossible to be explained in terms of FSI alone, $\epsilon'/\epsilon\sim16.5\times 10^{-4}$ is obtained through FSI, if the calculation is concernedonly with the CP-violating parts. The pi-pi contribution to the m_L-m_S massdifference is shown to be about 0.14, if the sizes of the CP conservingamplitudes A_0 and A_2 are correctly given.Comment: 6 pages and 2 eps figures, LaTeX
