First thing I would verify is that the pump is acting correctly. Turn the
key to ignition and verify the pump clicks for a bit and then stops. "A bit"
can be very short if your fuel system is in really good shape. If you don't
hear anything I'd check the ground inside the boot behind the license plate.
If it clicks a lot and doesn't really stop (Paul's timing is correct) then
check your carbs as you may have a sticking float or needle valve. This
generally includes lots of fuel smell as well.

Once the carbs are full the pump shouldn't click more often than once every
30 secs, and in practice less frequently than that, until the engine starts
and you start using fuel.  Flooding it will use fuel of course, but cranking
speed is much less than a cold-start fast-idle speed so usage will be
correspondingly less.

Condition of plugs, points?  State of tune of ignition and carbs?  Choke
operation (possibly OK if it flooded)?  Induction leak (possibly not ditto)?

If the plugs are flooding it points to an ignition problem more than a fuel.

If you have a timing light clip it onto the coil lead and each plug lead in
turn and watch for regular flashing while cranking.  While on 1 and 4 check
that the timing is around 8 to 10 degrees BTDC.  Note that if you have a 12v
powered timing light the reduced voltage during cranking may not be enough
to work the electronics, so you will have to power it from an alternative
12v battery, either a charged spare or another vehicle.  If you have the
old-fashioned orange neon 2-wire timing light this should work in any event.
