Can't see how, even if the power valve is open, the PVCRs in parallel with main jet is the same as the total areas combined.

A blown power valve feeds fuel directly to the intake manifold, via the vacuum channel in the throttle body.

The bowl drains into the motor at shutdown.

Excessively high float level IS THE ONLY WAY fuel can run from the boosters.

All carburettors will have this problem with an uncontrolled float level.
