Does Mercury Carb Gasket kit contain airbox/attenuator plate gasket?

[Nathan Bond]

Dumb question, but all the pictures I've seen of the gasket kits for my carbs show only 1 round gasket for the manifold side. Do I have to order separate gaskets for between the carb and attenuator plate?

Here's the kit I am referring to: http://www.iboats.com/Carburetor-Repair-Kit-Sierra/dm/view_id.174829
