Small Engines (Lawn Mowers, etc.): part numbers, sears, craftsman

Question
I'm trying to get part numbers down to the carburetor part number level for my Craftsman alternator (580.320480). When I get to the engine number (45613) Sears says the part is discontinued and no more information is available.   Can you help me identify the carburetor and parts list?

THANKS
