How can you determine motor build date . By serial number on motor?
correct the engines build date is the serial number, Your pic above is kinda small it looks like its 106, maybe 7? and them the shift/assembly line Letter. So first digit (1) indicates 1971 as they used the last digit of the year, 067 is the day of that year March 8th 1971
...Frazier vs ALi in Madison square garden happened that night, The fight of the century! Hopefully they weren't too pre occupied on the assembly line that day taking bets and smack talking :D

That was just for the engine and it would have left the Tecumseh plant as your basic run of the mill Enduro/Hustler engine complete. They would have pulled the throttle bellcrank arm pieces, and intake/carb/air filter assemblies off when they arrived at the Rupp factory. to install on a Blackwidow.
