I don't mess with it if it's only for a few months such as one winter. Put the thing(s) away dirty, drag them out when needed and fire them up.
I really don't think gasoline deterioration is the problem it once was, otherwise I would have been bit due to my negligence and the number of engines I've treated this way. The only carb I've ever had to rebuild was on a snowblower that wasn't used for multiple years.
