Carburator bowls are vented to the atmosphere. The gas in them is going to evaporate over a few weeks anyway.( That's why they install the prime switch. )
If you look in your generator manual, you may see that running it dry is recommended. Cummins recommends draining the bowl if it can not be exercised regularly.
In my experience, dealing with small engines for over 50 years, I've never seen what you say " can possibly happen " in a carburator that's been run dry.
Letting it evaporate slowly gives it more of a chance to varnish the float and bowl then running it almost dry in 5 minutes.
Gas, in fuel injected engines, stays in the fuel lines, and doesn't evaporate. They typically can be stored for long periods without problems.
