The needle for Mark V main carbs is listed as F.W. in the shop manual.
To the best of my knowledge Mark V carbs did not come with lifting pins. The shop manual pictures and description rely on the screwdriver lift method for checking mixture. Given the interchangeability of carbs, lift pins may be found on some now and are convenient.
Be sure to note the difference in piston lift distances described in various manuals for determining mixture richness. Different piston lift heights give different outcomes. Haynes, SU, and the Jag Mark V shop manuals do not all use the same lift heights.
