Would that make the engine spin the other way ?
I don't know why that would be required, but it looks like
it...

the direction of a 4 stroke engine's rotation is dictated
by the camshaft. Ignition timing plays a part as well but
to a far lesser extent.
I would guess the engine was used for a stationary drive,
perhaps a generator or pump. The gearbox has been cut off,
the flyweel left but sans clutch. Might be a marine
application too.
