Personally I would never store and engine with a dry carb. If the gaskets dry up and shrink you will have to rebuild it, not just clean it.
I use a double dose of StaBil and have never had a problem storing my engines over the non use season. I just got my 2000 out last week from spending the winter in an unheated shed. Fired right up, got her good and hot and changed the oil and cleaned the filter. Ready for another season!!! :C
The same for my lawn mower and chipper vac. No problems. My snow thrower spends even more time in hibernation as we only have a couple snow months.
Just be sure to run the engine long enough so the StaBil mixture can fill the carb before you shut it down. :)
