Not any photos are complete carb kits, and not knowing what brand of carb they fit doesn't help but:
#1 could be either T 6173A, B, or C Air valve shaft assy for Kingston L, L2, or L4. cork plug is T 6171C for L4 carb.
#2 has another similar part to #1, plus a drain valve body and valve. Kingston number for drain valve, 6169E. Holley G, NH, and Vaporizer used 6216 for valve and NH and Vaporizer used drain valve body, either 6216-21 or 6216-91.
#3 has Viton tipped needle and seat for unknown carb. Viton tipped needle and seats are not available for Kingston and Holley G carbs. NH and Vaporizer carbs use 6212.
That's about as close as I can figure.
Thank you, Terry.
