Started taking my carbs apart this evening for a clean and to fit the new jets.
I've confirmed they're UK with metal slides, however, the needles, emulsion tubes and jets seem different from standard and I'm wondering if anyone can help me out with any info please.

Front needle


Front emulsion tube and a main


Rear needle


Rear tube


There is no I'd / writing on any part except the number on the mains which is 114, no manufacturers mark, nothing.
As you can see, the needles are adjustable and have a very different taper from standard.
