I recently purchased a B&S 5hp flat head and it came with a different carb setup. I would like to replace it with the stock setup that has the fuel tank under it. I have searched and searched with nothing found. There were a few on eBay and they looked as if they were sitting in salt water for 50 years and that's something I don't wanna have to deal with lol. Can anyone point me in the right direction please? Thanks.
