Unfasten the nut and you'll probably find a fuel filter.  The leak is
probably not oil, but dirty gas.  Fix this - a rebuild kit should
include a new gasket, or make one yourself out of gasket paper.

AFAIK, a hose from the oil breather should attach to the air cleaner,
not the carb.  I believe the oil breather is basically a crankcase
ventilator.

Sounds like the accelerator pump.

Sounds like an idle set screw.

Probably idle mixture.

Dunno about that one.

Ditto.  Need a better description, including what "front" is.  A better
way to orient ourselves is to describe things relative to the side that
the throttle attaches to.  Those carbs mount in all different directions
on different engines.  On my Capri it actually mounts at about a 15
degree angle.

The choke consists of the plates in the venturi and a mechanism to
control their position.  This mechanism is usually a coiled spring which
is heated either by engine coolant (but not in this application!) or an
electric heating element.  Look for a round flat-ish canister with a place
to attach a spade terminal.  There should be a metal ring around the
outside with three screws in it.  Loosen the screws until you can swivel
the canister.  Turn the canister so that the choke plates are horizontal
(i.e. closed) when the engine is cold and vertical (open fully) when the
engine is hot.  That's not a very good description but I hope it sort of
explains it.
