I wouldn't paint a pot metal carb. I have painted Zenith carbs with lacquer and had good results.. NAPA use to sell a product named triple etch that will etch alloys, I'm pretty sure that they still do Rustoleum will probably wash right off with alky-rub gas . Why not try the Snyder lacquer paint that Mitch shows. I have purchaced black lacquer in spray cans at Advance Auto Parts, Auto Zone and sometimes Walmart . Its your project and your choice .
