I just intalled new door handles and I need help

That adjustment is exterior door handle linkage, not lock cylinder. And I forget exactly how that adjusts. My memory fails. It might be just loosen the screw so to let the linkage settle, springs do what they do, and tighten again. Not much angle up/down adjust would happen through a small round hole anyway.
You might find better info in a service manual. Good luck
Thanks, I checked the service manual but it`s pretty vague at best :)
