The picture shows the simple tool I made which makes measuring the height a cinch. It is a short piece of stiff wire (actually piece of coat hanger) with a notch at 24mm (28mm for 40mm carburetors).

I always get around 22.5mm doing it that way. Time after time with no problems whatsoever. AFAIAC, 22.5 is what it 'should' be. I call it 28/32nds. I have been making that measurement with a machinists ruler for decades. It wouldn't be the first time my experience does not add to snowbums but at least his 24mm height will work.
