Are you looking for the correct 533A stamped carb, or would you be ok with the more common AT7B carb from a K0 model? I don't think I have a spare 533A. I have several AT7B carbs I would sell but would need to be rebuilt as the gaskets and seals will be rock hard. I can rebuild it with an oem honda kit and test run it on an engine for you, but the cost will increase.
