Carburetor Gaskets Leak

The gaskets on the carburetor of my 55 series one Chevy truck leak. Is there some kind of gasket seal that I need to use on them to get the leaking stopped?

Thanks for any advice,

Assuming you mean a single barrell Rochester. The bowl gaskets are quite thin and really wont seal any imperfections on the main body or the air horn / bowl cover assy unless you take the time to make sure both mating surfaces are perfectly flat and clear of pits, etc.

Laying a piece of 220 to 360 grit on a sheet of glass and running both mating surfaces over it will help give them a true and flat smooth area for the gasket. Of course the carb should be totally apart for this and cleaned real good before reassembly. Make sure the float level is correct too and that will help. Also resist the urge to over tighten the bowl screws when reassembling. That raises the thread boss and actually lifts the air horn assy off the bowl causing a leak.

Gasket sealer or cement isnt a good idea on a carb as sooner or later the gasoline will soften it and it could manage to clog up a jet or metering rod passage.

If your carb is severly pitted on the mating surfaces or too badly warped to correct you could get another used one from a salvage yard. These are among the cheapest of used carbs.

Hope you can find this useful.

Thanks for any advice,
