I’m trying to rebuild a carb for a 1947 Evinrude Sportwin 4421 and I’m wondering if anyone knows where I can get gaskets and a float. Im sure I can make gaskets for the top covers (p/n 170098 & 171073) but I don’t know what to do for the float (p/n 170336) and the needle gland packing (p/n 171113) I have attached photos to help identify the parts. Any ideas are welcome….thanks!!!

As you say, the gaskets are not that difficult. Many are adapting the mercury float, as in the illustration. I had a collection of punches and punched out needle valve packing out of the neoprene impregnated cork I used to make fuel tank gaskets. The cut out in the center of the fuel tank gasket would make dozens. a stack of three or so would keep the valve from leaking and hold it in place. Do not allow the packing nut to bottom out. over tightening will break out a part of the threaded portion and render the casting useless.
