Explanation

momentary/moment.s delay will replace moment delay. Both moment and delay are Nouns. But an Adjective/or a Possessive Noun is used for modifyinga Noun.
`{:("a momentary delay /a moment.s delay will be used"),(" "darr " "darr " "darr " "darr ),("Adjective" " Noun" " Pos. Noun" " Noun"):}`
Hence, A moment.s delay/ A momentary delay is the right usage.
