Can the wrong fitment of a throttle cable stop an engine from starting ?

I ask as the last I remember just before I gave up with the bike two years ago was it not starting after fitting a new throttle cable, it still won't start and I have done everything else- clean fuel, cleaned carb twice, I have a good healthy spark and the air filter is not blocked, but it won't start.

Removing the spark plug and cranking over it is clear no fuel is getting to the combustion chamber, but there is nothing wrong with the carb, so I can only think back to two years ago and I gave up because it wouldn't start after fitting a new throttle cable, so is the problem the cable somehow ?

Is there a special procedure to fitting the throttle cable to these things ?

The routing is correct and it's not trapped anywhere.
