For storage, I've wondered how useful it would be to have either a fuel petcock valve on the line, or if one wanted to get fancier, a solenoid activated fuel valve (so it could be turned on/off from i...

This is a tough one . I used to run carbs dry on small engines but a good bit of gas stays in the bottom of the bowl and aluminum sweats it mixes with that gas so the next time you run gas in it it just mixes with it .
On lawn mowers or gens that are gravity fed i leave the fuel full in the carb but cut the petcock off so if your are hauling it when it bounces up and down it will bounce the float and flood the engine . When i'm ready to start it back up drain the bowl and open the petcock to fill the bowl back up . A full bowl while your not running it will not sweat as much .
On a gen with electric fuel pump i would leave the carb bowl full for the same reason but you don't have to worry about bouncing up and down because you usually have a fuel solenoid . Same thing if its down a long time just empty the bowl right before your going to run it again .
When you empty the carb bowl on new start you can open the petcock or prime button and run the gas out of the fuel hose to till the gas looks good you can tell by the color .
If its going to be yrs before you run it yes empty the bowl take bowl off and wipe the bottom out clean blow a little light air up the main jet to get it dry . Hope this makes sense .
