It's an updraft carburetor. The gas/air mix has to move upwards a few inches to the intake manifold to get into the cylinder.
There is absolutely no way for that quantity of gas to flow from the tank to the crankcase through the fuel system without involving cartoon physics, or one-in-a-million circumstances:
Normally if the float was sticking on the carburetor and gas was pouring through, it would start to run out through the air cleaner hose or a drain in the carburetor. Theoretically, if the tank were full, the drain plugged, and the air cleaner hose sealed, the gas could fill the air cleaner and intake manifold. However, when he tried to start it, he should've gotten a gasoline shower because the intake manifold and air cleaner would be full of gas too! I would think that he'd mention getting soaked from head to toe with gas when he went to start the tractor.
How would you get that much gas in the crankcase without something being obviously wrong? I don't know. It shouldn't be possible. The tractor would have to have been running poorly for quite some time under heavy use to pump that much gas vapor up and over the side of the engine. THAT is why people are skeptical.
Frankly, I think he drained 2 gallons TOTAL out of the crankcase, which isn't much more than what a C169 engine holds normally. It smelled like gas because the engine had some blowby. Maybe there was some raw gas in it, but not 2 gallons.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
