More than likely, you have a good engine and you are just hearing the compression push past the rings and into the crankcase and out the vent. The engine stops turning when it hits the last compression stroke that it can't "push" through, so it always stops with pressure in the cylinder. What you are hearing is actually good news.
Only other thing that crosses my mind is a leaking head gasket, but you would most likely hear that when it was running.
It's not the carb.
