Carburetor gaskets

[Lutz Kramer]

I have an AH 3000 BJ8 with two SU HD8 carburetors. I found 4 gaskets for each carburetor in the following sequence:

air filter -> gasket #1 -> carburator -> gasket #2 -> heat shield -> gasket #3 -> insulating block -> gasket #4 -> inlet manifold

Gaskets #1 to #3 are paper gaskets, while #4 seems to be made of a kind of a metal, which has a lot of factory made press-fit recesses (the best I can describe it).

Question is, whether this kind of seal ist original, because I couldn’t find it in any oft he parts catalogues and whether it seals air tight without using a sealant like for instance Hylomar?

The way I understand it is the metal gasket has an insulating material in it to help insulate the carburetors from the heat of the manifold . I just assembled them all dry . The metal gasket will crush like a head gasket to create the seal needed .

Thanks Healey Nut, but who offers these special gaskets since I couldn't find them in the catalogue of Moss, Limora (Germany) and Bustuck (Germany)?

no longer available. ahead4healeys show a photo of the original type but when you get them delivered and they are the paper type they say that's all you can get now I could not get them anywhere they were going to remove the picture and show what is available don't know if they did

 

[Healey Nut]

They have always been in the head gasket kits that I have bought .

I guess, I'll take the old gaskets with some Hylomar and that will do it, because I think it's not a good idea to use paper gaskets right next to the exaust pipes.

Lutz,
If the gaskets you're referring to are the standard graphite-grey paper types used in the area of the carb, heatshield and spacer block, don't believe one of them has ever caught fire. Everyone's been using these forever.

 

[do8erman]

there safe the thick insulation block is there to take away / absorb the heat also they are a wax type fibre

Lutz--

As pointed out by others there is no fire risk. Instead of Hylomar use Permatex Ultra-Copper (Hi-Heat).
