I am in the process of overhauling a carb (first time doing this) on a B&S 8HP engine. Its a float bowl carb. I ordered the rebuild kit and it came with three gaskets, two of which are identical in shape, but are made of different materials. The identical gaskets are for the bowl to upper assembly connection.

Do I use both of these gaskets, or just one? A picture of the OEM B&S kit on the web shows two gaskets, so I know that both are supposed to be there.
