I didn't find anything that discusses a gap or mechanical clearance adjustment, if I'm understanding your post correctly.
Thanks. I thought I had seen that in the factory service manual for my 90 but maybe saw somewhere else. I'm guessing you want that gap to be as small as possible without the plates binding in the bore and let the IAC control idle. I suppose if the gap is to big, the IAC can't compensate.
