Ive never heard of any damage happening. During the initial cranking, most of the carby cleaner should exit through the exhaust before the engine actually starts up (which takes longer than usual obviously). Cranking is run off a 12v electric motor rather than the powerful force of combustion, so it should be fine.
If you are worried about it, simply remove the spark plugs so the cylinders can breath and avoid a hydrolocking scenario.
