Only if you want to the answer to the question
"WHEN does cut out occur?"

(For this reason, normal turbulence would seem quite unlikely to produce cut behaviour.)

Yes, it certainly will produce a cut out if the acceleration reaches the threshold.

As soon as the g level falls below about +0.1 indicated, the float stops floating properly, and the carburettor therefore stops metering. Exactly what reduced positive g will cause misbehaviour will depend upon the friction in the system and any slosh in the float chamber, leading to slight variation on a case by case basis; but this sort of detail is way beyond the scope of a simulation of this nature.

Once again, in an engine consuming 100 gallons per hour, the tiny bit in the float bowl will not last a cycle....
Even in a lycoming consuming 9 gallons per hour, a cut out and rpm change can be heard in turbulence or any negative acceleration.
Where do think kids get the airplane engine noises, "WAAAA waaaaaaaa WWWAAAAAAA" when playing from??
