How long do you think a few ounces of fuel last's in a WWII fighter engine consuming 40-160 gallons per hour?

Even in a Lycoming O-360 A1A consuming 8-12 gph, the consumption is high enough and the cut out is for intensive purposes, instantaneous.

Certainly in a climb a float type carb will react if subjected to negative accelerations. In normal climbs, a gust or turbulence acceleration is rapid onset and very short duration so the skipping is not noticed by most pilots. If you have a digital rpm and manifold gauge or an EIS you will see it.

Bunting was a common tactic used by Bf-109 pilots to escape Spitfires on their tail in fact.

A bunt is just a maneuver involving a negative g pushover, especially in an air-to-ground attack or leveling out after a zoom climb.
