are you trying to install a new 1/2 or 1/4 turn throttle ?? thats what it seems like to me.
the throttle/bar end of the cable is always the same, has the little nub on there to slot into the lever .... you can make small adjustments here but nothing major.
For the carby end you need to figure out what length you need, then resoldier the nub back on so it gets held properlly inside the carby.
