Check my throttle linkage

If I am reading this correctly, the cable does not have enough travel to pull the carb linkage all the way to WOT. Looking at the pics, there is nothing wrong with the cable/spring angles, even if they are 'non' stock. Spring is ok too, it has lots of coils, so not too strong at WOT.
Problem is probably the pivot distance from pri shaft centre to throttle cable pin on THAT carb. It needs to shorter by about 1/8".
