I just rebuilt a ’45 gale 3hp and could not find any vendor with carb kits prior to 1950. I ended up buying a cork float from Marshall’s Hardware for less than $2 and cut it with a knife to size. I cut my own gaskets from gasket paper. Used a punch set to make the holes in the gaskets. Found a washer/o-ring assortment case at Harbor Freight for $3 that had most of the stuff I needed and used dental floss wrapped around the needle and seated with washers for the packing. Made a new hard line from the tank to carb with standard copper line and compression fittings. Fired up on the 5th pull. No fuel leaks yet.
