AAZ throttle arm position ?

[ELVIS]

swapped over throttle arm for my AAZ conversion but dont appear to be able to get it 100% right , the only way i can get engine to rev ok /reach speed is to screw out factory throttle stop . is this ok ? seeing as max revs are governed by pump im not gonna do any harm am i ? if i am , how do i get back to factory settings ?cheers   elvis
