CEJ is richer on the straight portion by .01mm. This will only have an affect below 1/4 throttle.
CEJ is 2.68mm vs CEK at 2.69mm
-------------
The N85 question can't be equated to clip position because it is the portion before the taper start which is different. Again, only having an affect below 1/4 throttle.
N85D is 2.68mm vs N85E at 2.69mm
These both run richer than the CEJ/CEK because of the location of the first taper start (higher on the needle).
