Hello.

I am looking at a replacement carb for the ET4 125 (leader) that the website claims is ‘near identical to the Mikuni BS24’ and states that it is an adequate replacement for Leader ET4s which is what I have.

You can see the item here:
https://www.sip-scootershop.com/en/product/carburettor-naraku-24mm_NK200060?cr=3a6304bb-cc81-4ed5-9f63-1ff45fe1abfa&gclid=EAIaIQobChMI6_CDkYub8gIVDO7mCh1v5wHlEAQYBSABEgIUvfD_BwE

If you have looked at the carb you’ll notice the mount for the throttle cable is much further away compared to the cable mount on the original leader Walbro carb. The bracket to put the throttle cable through is right next to the throttle on the Walbro carb but the replacement carb in the link above has a much bigger gap between the cable mount and the throttle. This worries me as I fear the throttle cable may not be long enough.

Has anybody used one of these carbs on an et4? Did the original throttle cable still reach or did it require modification?

All best,
Ben.

The Naraku is basically a copy of the Keihin CVK. It has the same external dimensions as the 26mm used on most GY6 engines. You could easily find one to actually look at and see how it would fit just about anywhere Chinese scooters are repaired.
OTOH, You might be able to find the Mikuni via a KTM dealer or a copy on Aliexpress.
I think there's also a DellOrto 22mm flat slide carb that came on some of the early ET4s.
