Hello mowermechanic

The simple answer is ... probably, but not necessarily.
I would date this engine from late 1950s to mid 1960s.

Hurricane were lawnmower manufacturers in their own right from the early 1960s.
Originally (1950s) they were engine manufacturers to Australian lawnmower OEMs -
Amplion, Atom Mofast, Colda, Collect-O-Matic, Crowe, Precision, Pye-Tecnico, and more.

This engine could have been originally applied to vertical or horizontal shaft
applications (not necessarily lawnmowers) . With no provenance, we simply don't know.

Hope this helps.
