Possibly you could post a photo of this situation you are describing or maybe explain what you mean by choke up in some other words.
First thing you need to do is ignore the angle numbers printed on the semi-circular blue base plate. They are just a suggestion or a reference guide and not for actual measurements. All that matters is that the angle you want, needs to be the angle reading you get with your digital cube. Just slide or rotate the central angle lever right or left to move the black end brackets closer together for lower angles or further apart for wider angles. With the angle cube in place use the reading to get close to the angle setting you’re seeking. Then do the fine angle adjusting with the micro-angle adjuster knobs. When you dial in the angle reading you want on the cube, lock the adjuster screws in that position. When you’re done, it doesn’t matter what number the lever is pointing to, as long as your cube reading is on the angle of your choosing for your knife. The printed numbers are just a guide. Go with your angle cube.
If you run out of adjustment range with the micro-adjuster screw, then move the central lever one click in, (to the left) or one click out, (to the right) as needed to give you back some adjuster screw length. That is if the screws are backed all the way in and you need a wider angle, click the lever to the right, one click. Or, if the screws are out as far as you can turn them and you need a lower angle, still, click the lever to the left one click. If that one click change isn’t enough adjustment then do a second click. Then redo the micro-angle adjustments each side separately, using the angle cube readings. Each knife side is micro-angle adjusted independently. The adjuster screws may appear to be in different positions, comparing the left side left to right. That doesn’t matter. As long as your angle cube reading is correct on your desired set angle when checked on both sides, you’re good to go.
