FRANK - Sorry, Not DON, His wife has him out of the shop where his MAN CAVE and CUB's are.
For most of the engine the normal Cub Cadet 483 yellow works fine. Several others here including me prefer a semi-gloss to gloss black because it keeps the engine looking cleaner over the long haul. All the cooling shrouds stay cool enough the CC yellow holds up fine. Most people don;t paint the carbs because long term exposure to gas lifts the paint, and the coolig fins on the head and block should NOT be painted since paint is an insulator which causes the engine to run hotter and the paint would burn off the cast iron engine cooling fins anyhow. The crankcase protion of the engine can be painted. I leave the diecast alum. blower housing back plate bare alum. for heat dissipation also. And the oil pans can be painted but since it's effective as an oil cooler I normally don't paint them either. Thur the normal operation of the engine the oil pans get covered in oil & oil vapor so on cast iron pans they wont rust which both the oil and rust is an insulator also so I don't see the need to add a third insulator with a coat of paint.
Many have just sprayed on a thin coat of primer and a good coat of CC 483 yellow and their engines have lived a long happy life so whatever you do will work without special paint, just good preparation.
The cooling shrouds on my K321 I built 5 yrs ago I gloss back powder coated and anything else that was steel (gas tank mounting brackets, air cleaner cover & back plate) and they have fantastic durability. I thinned some semi-gloss black hardware store enamel paint to use on the cast iron parts and that has held up fine too.
