Title: Two-stroke ports for power
Description: Roy Bacon A.M.I.Mech.E. was an expert in tuning two stroke engines. This book explains the theory of a two stroke engine and how to calculate and modify the ports fr maximum torque and power. It was first released in 1967 and reprinted in 1968. I have owned a copy since 1967 and have used it to successfully increase the power of many engines.
