This is a good question and I was actually wondering that myself when I thought I heard a car, that I believe had a carb, backfire. I'd think at the very least you would need to have slosh tubes on the jets, and connect the vents together with a hose and put a small hole at the top of the hose.
The oil in the rear end was coming out the vent the first time I auto crossed. I would have never guessed all the oil in the diff would fill the tube to force it out the vent. I just have about 2' of hose coiled up now coming off the vent. That seems to have stopped it from leaking.

There's stuff out there to mitigate the fuel slosh thing, I was just curious. I've definitely had to stop short a few times, and had to pedal the throttle to keep it running when I did. I would imagine if I really wanted to be competitive in an event like that I'd need to modify the vents.

I run "seals it" seals in the axle housings I've redone, it depends on where your vent is located but if it's in the tube then the seals keep oil from getting that far out. They make generic versions too that are a bit less expensive
