I have a beautiful color reprint of the Lister  Gas Engine, saws and pump information manual. face stapled. Front and back are heavy duty card stock. It covers the small 2hp thru the 9hp vertical engines. Has info on the contstruction of parts like the piston, carb, and even the mag. covers several sizes and has alot of good pics. 25 pages. Has info on different pumps, pulleys and the lighting engine as well. Nice info about the engine. a great addition to any collection.
