Hi!! I need help with a couple of more old engines that are sitting in one of the buildings. I have not figured out how to attach picture here yet so I will have to send you to Photobucket, I hope. The first one has a casting date of 1 8 20, I hope that is the casting date and uses an Autolite single unit generator and ignition system. I can not see any casting numbers or serial numbers on the crankcase. http://i132.photobucket.com/albums/q6/naylorbros/IMG_1044.jpg http://i132.photobucket.com/albums/q6/naylorbros/IMG_1045.jpg http://i132.photobucket.com/albums/q6/naylorbros/IMG_1046.jpg http://i132.photobucket.com/albums/q6/naylorbros/IMG_1043.jpg The second one has a crankcase casting # 345709 and a serial # 2292277. I looks like it only has one exaust port for all four cylinders? http://i132.photobucket.com/albums/q6/naylorbros/IMG_1033.jpg http://i132.photobucket.com/albums/q6/naylorbros/IMG_1034.jpg http://i132.photobucket.com/albums/q6/naylorbros/IMG_1037.jpg http://i132.photobucket.com/albums/q6/naylorbros/IMG_1041.jpg I hope that the picture addresses will work. Thanks for any help with the id or either of these engines. Ken
