To use clecos, you insert the tang into the hole, press the cleco flush
against the visible part then squeeze the handles whilst maintaining a
moderate amount of pressure on the cleco. The pair of shaped wires are
squeezed past the tang and through the hole in the INVISIBLE part with
a slight click, telling you it's okay to relax your grip and go on to
the next one.

All right, I'm a confused newbie. So please, help me out, here. I'm told
that the correct hole for a 1/8" rivet is a #30, which is 0.1285". My
1/8" clecos, uncompressed or unextended, are measuring about 0.158",
rotating them in the calipers to find the maximum (diagonal) dimension.

I didn't have an experienced builder leaning over my shoulder when my
tools arrived, so I tried to figure them out on my own. Apparently, I've
been using the "wrong" technique, but I tried your suggested method, and
I can't get the 0.158 cleco through the 0.1285 hole. Do you have any
further clarification?
