The gasket may cause the fuel bowl to stick. Do not jam a flat-blade screwdriver or chisel between the fuel bowl and metering block, or between the metering block and main body.

Avoid digging between the fuel bowl and metering block with a screwdriver or chisel, as this can gouge the mating edges.
