BPE Kickdown linkage

Installed the Bouchillion performance kickdown linkage and have a question about the adjustment at carb. In the instructions is states "At wide open throttle, THROTTLE VALVE LEVER on transmission must move rearward against stop." So I set it up this way, however, when the carb throttle lever is at idle position the throttle valve lever on the transmission is slightly open (like not at rest and has a bit of tension). Is this a normal condition? Or will damage occur?
