Two Stroke Tuner's Handbook written by Gordon Jennings. In an attempt to acquire that understanding I
began a study of the high-speed, high-output two-stroke engine that has led to the
collection of a minor library of text books and SAE papers. And to an endless series of
experiments, some of them illuminating and many others raising more questions than
they have answered. At this stage I have arrived at more or less satisfactory explanations
for most of the gross phenomena, such as the general behavior of expansion chambers
and port time-area values, and I flatter myself to think that just that much is an acceptable
excuse for writing this book for the guidance of the layman experimenter. If it will not
supply all of the answers it will at least take care of the fundamental problems and
prevent the worst mistakes.
