I know the 2500S had BDB needles. And need the restrictive air filter setup otherwise the engine won't rev beyond 3000rpm. (Found out when I fitted a 2500S engine in my vitesse with free flowing filters)

So you need to match the needle to engine spec.

Darren,

If James Carruthers' Mintylamb site does not help, maybe call Andrew Turner, he should be able to give you a good guide.

Are the carbs in good nick?
