Did a quick search on another web site.

MB GPW Carb gasket to manifold w/ diffuser -A6357 + Vintagejeeps RFJP G503 MB GPW Part A6357 + Jeep

This is the gasket I use on my 45 2A. But a while ago, there was some issue about the copper "ring" on each side of the gasket not compressing enough and causing a leak. 

However, my 70 plus year old what is left of brain may not have this remembered this correctly.

Frank

	Frank your brain is fine. At least in this area it is! I can not say about the rest. Those copper rings need to be pre-crushed before installation. Otherwise they do not crush enough & they hold the carburetor off of the gasket material which causes a major air leak. BTDT.

	Cpt logger, Thanks for the positive vibes. Now I let my immediate supervisor know that at least part of me is okay. Frank

	Dumb question, but is the gasket the same regardless of Solex or W-?

	I think I read somewhere that when the L engines were originally designed, poor quality gas was often the case, hence the low compression. It has also been my understanding that the engineers of these jeep engines and others of the period, wanted the air/fuel mix hot so the gas remained a fine vapor all the way to the combustion chamber for easier ignition. Evidence, of course, is the "flapper" between intake and exhaust manifold. It works but you don't need the carb hot. As for the carb gasket, it makes sense to me that a thicker unit would insulate better than a thin one and there are other ways to enhance its effectiveness. Hot rodders back in the day used to sandwich a piece of aluminum plate between the carb and manifold. Also, plastic carb spacers under the base are good at blocking some heat from migrating up to the carb. All that said, my engine had a thin gasket when I bought it. I changed it to the proper thick unit with the metal thingy... couldn't tell any difference.
