<VV> carb gaskets and insulators

[Chuck Kubin]

    Insulator sandwich with a gasket on either side of the insulator, or thwe sealant if you see some sort of advantage doing it that way. 
  Brent's way is fine if all surfaces are perfect, but the gasket is there because things rarely are. Besides, do you want to troubleshoot your way through a vacuum leak  problem to go back and put the gaskets in later?

I never use the gaskets, just the phenolic plastic insulator all on its own.
and this has always worked just fine. If you like, you can put a tacky
coating of fuel impervious sealant (no thicker than paint) on the insulator
to be doubly certain theres no vacuum leaks but they do seal just fine dry
as a rule. Everything has to be CLEAN for this to work, make sure theres no
old gasket residue etc on the seal surfaces, and dont overtighten the carb
nuts, as this can crack the insulators or distort the carb casting.

Hope thats some help,
