MG TD TF 1500 - Seal stack for carb bowl

Hi all,
I can't understand why SU recommands this stack of fibre/metal/fiber.
Why would it be more tight than one (or two) fibre washers ?

Any idea ?

As always, pics would be helpful so we can know ,without ambiguity, what one is specifically referring to

Bill,

I think that Laurent is referring to the method used to fix the carb. float bowl to the body. It uses two fiber washers with a metal washer in between them.

Laurent,

I am not certain but I have a theory as to why this is done.
I will hold on to my response until others give their inputs. To understand my idea you need to think of chemistry.

Chemistry ! The mistery is growing...
I thought the metal washer was acting like a lip, increasing localy the pressure on the fibre washers. In that case it should be smaller OD than the fibre washers.

Well John, no other explanation. So I'm curious about yours.

FWIW - I believe that the fiber-metal-fiber stack was replaced by rubber seal in MGAs.
