Hi Paul;
You did get a good deal!
The valves in the throttle plates are decel valves or as the English call them "bypass" valves. They leak and cause an unstable idle.
The hot start valves should have a hose on the brass tube to direct any liquid fuel that may appear if the needle valve sticks or the float sinks, away from the engine. Leave the end open to the atmosphere. That valve is actually used to vent the float chamber, alternately to the front face of the carb at high rpm, and to the charcoal canister at idle.
Unless you live where it's really hot in the summer, the phenolic spacers are not needed.
