1960 Mercedes-Benz 190b (gasoline sedan).
Engine has "issues". Cranks fine, good spark, good fuel flow to carb, but tough to start and very rough idle.
So: carb rebuilt (cleaned, new washers, gaskets, etc.) new plugs, new wires, new rotor, new dist cap, new coil, new condenser.
But ... no fuel is getting to the plugs.
Fuel bowl is filled to correct height. Fuel squirts into throat with accelerator pump (and gas pedal). Linkage opens/closes butterflies. Checked but found no vacuum leaks.
Crank it with choke full on, fires once or twice, then just cranks merrily away without firing. Once this morning it idled roughly for about a minute, then just died. Crank it with choke off - doesn't fire at all.
Pull plugs. Completely dry.
I *want* to say a chipmunk built a nest in the intake manifold when I had the carb off - but that's too easy.
What am I missing? Jeez this is frustrating.
Thanks.

PS - classic M-B guys all say "rebuild the carb!" "change the fuel filter!". Did all that. grumble grumble
