In my opinion you are good, if the idle setting on the spindle is the same as factory. Weird that both the idle setting and the A/C idle diaphragm arm are both different from what I have.
For the diaphragm arm, at idle when my A/C kicks in it draws back and pulls the throttle bringing up the idle speed. You can see there is a gap which is different from yours. When activated it pulls the throttle back about 1/4 inch. I'm sure there is a service manual setting which I ignored. The effect is an rpm increase.
Of course, there are a ton of people here with more knowledge, I just know what worked for me. If I can measure something or more pics will help let me know.
