I have a good, clean gas cap with vent screw. It needs the cap gasket and possibly a vent screw gasket. Original vent screw gasket may still be good. The cap is from a late 30’s to early 40’s Neptune 1.2 or 1.5 hp. The teardrop tank looks identical to the Cub tank. If someone can confirm it fits, I will need your contact information. I already emailed a response to your classified.
