The Honda routine gets you to adjust one airscrew/idle metering at a time to produce the highest rpm while adjusting that once screw. It does not ask for or dictate a final screw position, just gives an estimated start point of 1 1/4 turns out.
When you've done one cylinder, then correct the idle with overall tickover stop screw. Then do subsequent cylinders the same by repeating the routine.
It's trying to produce the same mixture for each cylinder at idle irrespective of hardware variance.
If you reach the inner or 3 turns out position without reasonable response, it would indicate that the idle jet was wrong size (possibly non std air filters) or that circuit is not clean. This should pinpoint a dirty idle circuit with dismantling or guesswork as well.
