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. This can result in gouges at the mating edges, which potentially create raised burrs that prevent proper sealing during reassembly. A light tap with clesn plastic hammer pops it loose. Avoid digging between the fuel bowl and metering block with a screwdriver or chisel, as this can gouge the mating edges.

If you how to plant crown vetch seed to save the original gasket, carefully peel it off the metering block. Several small dowel pins locate the gasket.

Granted we don't have pics so I don't know how bad it is but I have a shelf full of those blocks that I use for pratice with modding.
