RD350A Over reving

[stuard]

Hi all.
I've just stripped both carbs and put back together. Managed to get her started, but one pot (non choke side) is massively over reving. Can't see owt obvious, sliders slide etc, had apart, several times but no joy.
Any clues to go at for me?

Is the cable caught up at the splitter sometimes the outer pops out causing high revs
