Try removing the cables Graham and blipping the throttle by using your hand on the butterfly. If it doesn't do it, then the problems the way the cables are routed or the way they are connected, sometimes easy not to leave enough slack in the cable or the cables sticking.
You checked the throttle stop screw on the butterfly? it's an eccentric cam arrangement and if it's out it will hold the throttle open even with no cables attached.
