Champion 2000 w Dual Fuel Generator
Any Champion Generator owners out there that can answer this.. My other generator is a Yamaha 2000IS and when I wasn't going to use it for awhile, I just shut the fuel valve off and let the carburetor...

The problem with shutting off the vent is it relies on creating a vacuum in the fuel tank to starve the fuel system. If the fuel tank is not absolutely rigid, it can collapse a little providing substantial amounts of fuel...as a result it may take a long time under negligible load until it sputters to a stop.
This will vary a bit depending on if it's gravity fed or fuel pump fed. If it's fuel pump fed, it will likely take longer as it can create a stronger vacuum before fuel stops feeding into the carb.
A fuel shut off valve should be just prior to the carb, so as soon as you shut it off, the carb almost immediately starts using up the remaining fuel in the fuel bowl.
For shorter term storage, on our yamaha, I do just use the fuel shut off. I do stay nearby and when it starts stumbling, I pull the choke to get a bit more fuel out.
For longer term storage (like over winter), I pull the panel and drain the bowl directly.
