2 possibilities:

1. The float needle inside the carb is stuck in the open position. This allows the weight of the gas in the tank to push fuel up through the carb into the intake tract, oftentimes resulting in gas filling up the airbox. To fix this, you need to remove the float bowl and ensure the needle and seat are clean and clear of any debris.

2. You have transported your Recon in your truck or on a trailer and the air passing by the snorkel drew air from the carburetor into the airbox. This happens because as air passes the snorkel, it creates a vacuum in the snorkel, airbox, and the entire intake tract. This vacuum literally pulls air from the engine backwards through the intake, carb, airbox, and finally the snorkel. As the air flows through the carburetor, it draws gas from the carburetor, carries it, then deposits it into the airbox.

You can purchase a "screw-in" plug for PVC pipes that basically expand as you screw the plug in.

You can see them here.

Or, if your snorkel is big enough, you can plug it with a tennis ball.

Turning the fuel off helps a great deal. It limits any possible "spillage" to what's in the bowl, which really is a tiny amount considering that the bowl is mostly full of the float and only a little bit full of fuel. This should be standard practice any time the machine is trailered or carried, regardless of the snorkle. Also when you park the machine for more than a little while. Occasional "incidents" are quite normal, and while not expected every day, they do happen due to random chance on a machine that has absolutely nothing wrong with it. Trouble is, if you don't check for it, you never know, you're driving with dilluted oil, you're trying to figure out why there's two gallons of gasoline spilled on the garage floor.

Capping the snorkle will also help tremendously. Either the intake or exhaust valve is closed at all times, so if (when) the wind blows across the snorkle and creates a bit of low pressure in there, it sucks the fuel out of the bowl through the jets just like a drinking straw... Capping the snorkle will prevent that little bit of fuel in the bowl from being pulled out of the jet, but it should not replace turning off the fuel during transport.
