Thick gaskets are a popular way of reducing engine heat from over heating the carb and boiling the fuel.
The thick gasket becomes an insulator between the intake manifold which is heated by the exhaust and the carb.

Thanks for the response! I wonder if I can get the bigger gasket somewhere.

There are thicker gaskets. The one that came with my carb rebuild kit was about 5/16 thick.
