383 tune up advice needed

Back to basics.
That carb had a looooooong trip getting to Sweden. Bounced around.
- You need to check float level, which should be 7/16". You will NOT need gaskets if you are careful. With the top still off: [1] Remove a secondary booster [ 2 screws ] & turn it upside. It will have one or two brass tubes sticking out. Look at the end of thicker tube. Is it cut off flat or bullet shaped? If bullet shaped, measure the hole in it. Post a pic if you can. [2] Flick the velocity valves under the boosters to make sure they are not binding.
- Make sure the acc pump squirts fuel into each pri bore when you move the throttle lever.
- Take a vacuum reading at idle, in gear if auto.
- I would get new plugs, NGK BP5S.
- The Torker is a single plane manifold which typically needs richer jetting, but before that...
- There are little covers over metering rod pistons. Loosen these, swivel slightly then lock in place so that piston is retained but you can see it. Warm up engine, idle, in gear if auto. The pistons should stat DOWN & not move. If they move, you need softer piston springs [ Edel sell them ].
