You need to see that the "dead-stop" will allow the KL to move sufficiently to achieve the change you want. So don't just crank away at the nylon tuning nut in the end plate, look underneath and find the screw that restricts the KL movement and adjust until the the pull rod can get the string to F#.
1. see that the nylon tuner nut
just clears the finger "at rest".
2. operate the KL and adjust the dead stop until you can get to F#. You may have to do this lying on your back underneath if you can't support the guitar upside down and still hear the string. A case of - turn screw a tad, check; turn, check; turn. . . etc.etc.
3. give it a very small additional turn (maybe an 8th of a turn, no more, will be enough) for clearance.
4. sit at the guitar and fine-tune using the nylon nut.
If that's too long of a KL move, you may need to hook the pull rod onto a different bell-crank hole further away from the body of the guitar.
Hope that's clear???
