No. It should be clean. Sometimes a very thin coating of grease is used, but never any gasket sealer.

Suspect you have a vacuum leak somewhere else. Or, this carburetor can be adjusted to give a larger accelerator pump shot, which may be what you need to eliminate the hesitation. It's also possible that the carburetor is jetted a little too lean for your engine. Ask Gronk about this.
