Carburetor Gasket + Form-a-Gasket...sloppy?

I'm in the midst of an engine overhaul and just disassembled and cleaned my carburetor. I'm getting everything ready for reassembly and I wanted to get a sanity check on the gasket. I ordered a replacement from Moyer and I have some Build-a-Gasket from Permatex laying around. I covered the paper gasket with a coat of Permatex and it seems a bit sloppy:

Am I doing this correctly? Did I use too much Prematex or cover a part of the gasket I shouldn't have? It didnt seem right to leave exposed paper/cardboard exposed within the carburetor without some sort of protective coating.

Any feedback is greatly appreciated, thanks!


Chris

The carburetor gaskets should be used naked

I cant recall right now what tiny hole you could block ?

Really, naked? The old gasket that I removed felt like a rubbery type material...wont the paper get beat up with the high temps and interaction with fuel?

I may have another gasket laying around, or do you think I could take a straight edge and scrape off all of the Permatex from the surface?...

Generally gaskets should be used dry. Only if you have a spot that is damaged and you need to use the old gasket, you might add a drop to that area. This also applies to engine gaskets that get much hotter.

"The old gasket that I removed felt like a rubbery type material..."
The last "mechanic" probably was unaware also.


"...wont the paper get beat up with the high temps and interaction with fuel?"
No

Tommays - some float bowls may have a passageway for fuel to flow for fuel enrichment (choke)

Simmon, a carburetor gasket will never get "hot" or even "warm". Consider that the carb is cooled by a constant flow of cold air being sucked in, and the fuel is hopefully vaporizing in there at the same time.

Flesh cooks at 106F, and you should never be able to burn your hand on a carb. In comparison, paper ignites at 451F--so your carb should not be a combustion source.

If you want to be sure about the assembly for that gasket, contact Moyer, ask them what they intended. A rebuild kit *should* come with instructions that also detail when and if any type of sealants are needed. If you need to, replace the gasket but I'd expect that any type of scraping on it will just destroy the uniform seal.

Pretty sure I got this tip from the Moyer website.
For the carb and other peripheral systems the gaskets do not require gasket goop.
The A4 manual says to use goop on only 1 side of the carb gasket. This makes sense as you WILL be taking it apart a lot more often than you might think.
Same for the water pump cover gasket, if you have the kind of pump that requires a gasket.
Head gasket - no goop required.

No goop period. I use contact cement very sparingly if necessary to hold gasket in place. Also teflon tape has caused me some carb problems when joint is disassembled subsequently.
