Here are photos of the gasket (with hole) and the crank case (no hole). Also curious is the fact that order of assembly is: gasket mates to crank case then the reed plate then the carburetor body. No gasket between carb body and reed plate. That effectively places a spacer (reed plate) between the carb and the gasket. The hole in the carb surface won’t mate solidly (unless the carb attaching bolts crush the reed plate into the gasket) with the hole in the gasket surface. Assembly order is as pictured in the parts catalog. Curiouser and curiouser.
