The rib of the rotor is about a 16th of a turn too far to the right.
Sounds like possibly a weak spring. Could be dirty also. Or both.
I'd say get out the Q-tips and solvent and clean from the top as best you can, work the rotor, wipe and see where you're at.
Then you can adjust the spring tension if needed.
Clean it and one click tighter spring should make it crisp.
