Mike Wills sent this picture of the Racing Beat engine
but it was too large to publish in its entirety so here is
a cropped version showing only the prop governor.
The red cap near the cog pulley is probably the prop oil supply to
the prop or oil from the pressurized engine oil system.
The blue anodized aluminum mounting bracket contains the
necessary pulley bearing I suspect.
