Engine Vin Number?

[Acolytus]

Could someone help out more about this old Tecumseh engine please? Is there a picture or website where I could match numbers? Thanks!

Post a pic of the whole motor and application but I would say 3-1/2 hp built June 26, 1979. LB-Biker has pointed you in the right direction for part numbers but check the OldMiniBikes Warehouse (link above) before buying anywhere else.
