There are copies all over the net of this book, including .pdf files.
Jennings book is probably the most popular, my original copy was lost in fire 20+ years ago, wish I still had it, the last copy I saw on ebay went for $128.Over the years I added several other books on the subject to my library, the two books mentioned below are helpful.
Other books on the subject of two strokes that should be digested.One is A.Graham Bells book. Although he disagrees with Jennings on the value of time area calculations, (programs and computers to crunch the numbers were not available at the time the first edition was published 1983)it is a good resource.Amazon new for $27
If you have a strong math background: The Design and Simulation of Two-Stroke Engines by Gordon Blair is a must read.
His software takes the work out of time area calculations.SAE $200 new for book and software.
