I have a beautiful reprint of the A O Smith Motor Wheel Gas Engine Instruction and Care Manual. 26 pages. face stapled. Front and back are card stock. This manual has all the information to take care and run a smith motor wheel. 6 drawings in the manual, with the center pages being a great detailed drawing of the assembly. Pages of valuable infrormation on the operation and care of the engine and motor wheel. All the info about the engine is there. It is a rare manual as it is the only one on Ebay. Don't guess on how to do it, buy a manual!! Has a basic description of the motor as well as set up starting and running as well as do's and dont's for the engine.  Nice info about the engine. a great addition to any collection.
