    I have never had to replace the carb to bowl gasket in my several cleaning rebuilds, but now I have a set of carbs that need gaskets.


    I have black fuel/oil resistant RTV, Indian Shellac , and red spray high tac.

    what sealer/cement is best to use?

    can I use the Indian shellac ? it is my go to gasket cement in auto applications.

    what do you use?

    I just use new gaskets. You can cut one from a cereal box if need be.

    i lay a sheet of 1000 flat on the table saw and make a few figure 8's lightly to check for high or low spots then put it on dry, seems to work for me

    I use rtv and glue gasket to the bowl , and light smear of grease on the matting surface to carb body . Makes it easy to pull bowl and does not stick gasket ,so it won't tear gasket.

    Be a
    Be aware that gasoline will soften or dissolve most silicone sealants.
    Just make sure the carb and bowl are clean and the gasket will seal just fine. The carb bodied have a small ridge built in that helps sealing against the carb bowl.
    If you are worried about the gasket sticking apply a thin smear of grease . They will come apart easy the next time.

    Tha gaskets are meant to be put on without any sealant or dressing. As mentioned, a thin smear of grease on one side is fine.

    May or may not be applicable to your situation, but I get the high quality aftermarket ones from Len and I never have to put anything on them.
