Just wait until you get the plastic carburetor that Briggs is now using on some models. You definitely got to have a light touch when tightening the screws or use an inch pound wrench.
This particular primer setup is a known problem maker. First even when new the installer can over tighten the mounting screws warping the plastic base. Then over time these bases will warp from heat, natural shrinkage of the plastic, and even the pressure from the air filter seal. These causes results in the cupping of the sealing area. Though not visible easily but it is there nonetheless. It can be easily checked for by installing a new gasket, lightly tightening the mounting screws, and then removing the base to check the impressions left on the gasket.
You find the old gasket is usually still sealing until the base is removed. This is due the paper gasket decompressing and keeping the seal. This leaves techs not familiar with this process scratching their heads as "It worked before I remove the base, why won't it work now." thoughts.
I have tried over tightening the screws to only severely damage the new gasket in one area and no damage in others. This is where it dawn on me to use a wedge gasket setup. Since I now get this gasket in AM it is cheap enough to use two when making the custom gasket.
