This book covers the Stover CT-1 CT-2 CT-3 CT-4 Oil Rite Engines. It has a full repair price list as well as all the operating and start up instructions. The book is clear and easy to read except for one parts diagram, due to the small size of the numbers they are hard to make out. But you can still figure it out with the help of the complete parts list to reference it to. Well put together and covers a lot of material. It measures 4" x 9". 12 pages.
