clearly not been fitted properly. Does the cable go into the carb onto a slide or does it fit on the side of the carband move a lever/bar.
When you twist throttle it should move a lever or bar on the side of the carb. Get a mate to check it. You can move this bar with you fingers and rev the bike dirctly from the Carb. Check to see if you can do this. If the lever/bar is not moving then the cable needs adjusting. Maybe at the throttle or the carb end. Did you defo get the right cable?
