Im rebuilding a set of carbs, the old needle set doesn't have the white seal, but the kit includes it. I just readjusted the float. Does it matter as long as the is set?
The nylon washer under the seat is OEM Evinrude. Included in float valve and seat assembly- 0396522
While you could probably get away without them, personally I would go back and install the washers as intended. It only takes a couple of seconds to adjust a float and it gives me the piece of mine that the carbs are assembled as designed. No second guessing yourself down the road
