Now the gasket and metering diaphragm do fuse together, therefore, can appear to be one piece.
Without the gasket between the main carb body and the metering diaphragm gasket your metering lever would set incorrectly if you use the W tool to set it; therefore, the carb would be over rich if not flooding.
This is a critical adjustment so much that I had to recently purchase the newer W tool for the latest carbs like the WTEA were the adjustment changes by the thickness of the gasket. Actually need to use the gasket to set those metering lever with the old W tool.
