The original subject was "Cushman upright 4 hp engine".
Anthony, for the Cushman engines there is precious little information to be had, and serial number info to obtain a date of manufacture so far doesn't seem to exist. I have a two cylinder C and spent much time trying to get info. There is somewhat of a date range determined by the intake valves, based on if the valve is tall or short.
