#1. The bottom unit screws into the threaded hole in the bowl cover. The top one is incorrect.
#2. If I'm seeing it right, the top piece is useless. Please show me your Metering Rod Tension Spring. It has a square bend.
#3. The brass tube is the main nozzle for a post-war carb. Most kits contain both it and war-time piece.
#4. The aluminum washer is placed over the hole that the Metering Rod passes through on the bowl cover. The rod passes through it as well.
#5. The hooked spring is the Choke Return Spring.
#6. If you are referring to the open threaded port in the throttle body you have two choices. If you have a Vacuum Advance Distributor, that's where the vacuum line hooks up. If not, plug it with a 1/8" NPT fine pipe plug.
#7. Your choice. Either will work fine. The one with the ball arm is for a motor with a belt drive governor.
Some light inspirational reading. Has pictures.
