1.6na injection pump questions

[Worldwide73]

This is side view of my pump.. what is the lever on the side for?  Is this causing my hard to idle when warm situation?  The other pump I have does not have this lever?  Do I need to modify this lever for the pump to work properly on my na?

thats a manual kill lever for a autotragic.... standard you dump the clutch...
