JW Carb rebuild kit.....parts identification

[Agordat]

I recently received an OEM carb repair kit PN 439071 for my old 3hp Johnson, JW11. To the best of my knowledge the carb has never been rebuilt on this motor since I received it new as a Christmas present when I was young. The packing and gaskets had all pretty much deteriorated or disintegrated. The repair kit includes sub assembly P/N 0439071 with an assortment of small parts. I am having trouble identifying some of these. I think I can recognize the 4 leather/fiber washers as the packing material for the high and low speed needles. I am guessing the two nylon washers go between the packing and the packing nuts. That leaves me with one small red (fiber?) washer, one thick leather washer and a thick rubber washer that looks like a donut. One of these should be the "boss gasket" that sits around the bottom of the high speed nozzle and forms the seal between the carburetor body and the float chamber. I'm guessing that the boss gasket is the thick leather one. I am also guessing the red washer is used with the float valve assembly and the donut is used with some other version of a JW carb. Can someone out there help with identifying these parts so that I use the right gaskets in the right places?
