I just started restoring this engine, but do not know the manufacturer and model. There is a tag on the front of the engine, which reads "Wettlaufer Bros. Limited, Toronto Ont., Can., Manufacturers of concrete machinery." There is a number on top of the water tank, 686958. I know that I may have answered part of my question but am not sure.
These engines have a compression release, and I think I need new rings and to rebuild the head because when I turn the flywheels I end up having more resistance on my Maytag Model 92 engine than this. Any information on restoring this engine would be very much appreciated. Thank you. Andrew Wrobel, 8725 Canal, Sterling Heights, MI 48314; (586) 876-8388; email@example.com
