Hey guys, I have a B&S (Quantum?) engine and the float bowl washer-sealer that goes around the nut it damaged. I believe the part number is 271716.

I did a quick search google/ebay and have found some, but they seem to located internationally and postage rather expensive.. even the washer itself is costly...

just wondering, does anyone know what material is used/needed for these washers to work? I can always get washers from bunnings or Buttsworths .. but they're usually steel/copper/other .. not sure if the B&S uses a specific material.. maybe some sort of gasket type material ???

Any feedback would be super.
