Good book about two stroke tuning. Often, two stroke machines seem to operate in a magical world, and only some magicians are able do tune and decipher information. While there are almost endless ideas, concepts, and tests that one can continue to do on two strokes and their various configurations, this is a handy book that initiates one into some understanding of the design, develops some practices that one to could to develop a repeatable engine package, and/or a reminder of some things that have been done and should be done.
Great value for the money.
