How exactly would the carb be sealed up?
You can seal the intake with a plastic bag and some tape. There really is no point to starting it unless you need to move it. As mentioned above you will cause condensation that could be worse than if you just leave it alone.
I usually run mine out of gas in October and put in fresh oil just to get the acidic oil out. I generally disconnect the battery and forget about it until April or May, whenever the weather breaks. Fresh fuel in the spring and I am off.
