Yeah, the first time you take the grinder to a carb, definitely feels a bit uncanny.
In general, if you remove about half the thickness of a standard Dremel cutting disc off the low end, and make the cut a bit "rounded" to by and large 1/2 of the total stroke, that is a good beginning for a single.
Just start carefully and gradually increase after testing. Do NOT go all the way on the testbench, because you cannot "ungrind", and engines need a bit more fuel in the air than they do on the ground, but it is not very critical. After I did about three carbs, I could basically do them freehand and end up near spot on.
A pic to give you an idea of how the final result should look, give or take...
ASP FS52. The original slot is milled therefore ends abruptly, it is unvoidable to cut a bit beyond the end, because the side of the slot needs to be ground to full depth.
It does not affect functioning of the carb or the throttle movement.
