goodo squizzy . the cam lifter (spider. never seen a three legged one but there ya go) will do it if its not in its three slots in carb body . cable adjustment too if the lifter isnt placed properly it can have that effect . cable has missed its hole and all it does is move full throttle to nothing .
follow the diagram and be sure the lifter is in place . not too hard just takes patients and a little harder if made up from others as they do wear different so its a matter of matching bits for the best outcome .
grooved face is for 125cc plain face is 160cc btw
oh and did you have the starter off ? sounds like a powertorque ?? if you did don reuse the large "o"ring or try n seal it just replace it as they can lead to start/running worries too
