stapled. 8 1/2" by 11". Front and back are card stock. It covers the small 1 1/2 hp to the 3 1/2hp Series W, WA, and WB engines. alot of good information about
all the timing, parts, carb, mag, as well as the care, starting and operation of the engine. Has parts listings for all the engines. a great addition to any collection.
