Vertimas - Italų-Prancūzų - Manca sollecita piu dell'usato

I would like to be able to edit this translation, but my Italian is too bad.
One thing is sure, it is that it doesn't make a lot of sense in French the way it is said, eg :
"il manque empressement"..."même que se balance"..."flamme que palpite" At least these three points are to be edited. And even once edited it still sounds weird.

I edited the target-language, but a doubt remains about the source-text

I systrannized the whole text and obtained :
"It lacks speeds up more of the used one ancorché s'agiti with light breath face that it palpita near to dying"

As you can see (and as far as I know, being used to check texts using the "systrannization", when some words are displaid the same in the frame from the target-language as they were in the frame from the source-language of the systranbox, it means :

-Either the words from the source-text are uncorrectly spelled

-Or the source-language is another form of the language (ancient Italian here or some dialect)

Je fais une proposition

Elle manque d'ardeur plus que d'ordinaire
même si elle se balance au gré d'un léger souffle
flamme qui vacille sur le point de mourir

Qu'en pensez-vous
j'ai utilisé elle car je pense qu'il s'agit de la flamme

Actually this text was already discussed (and extensively) here.
I based my translation in the Portuguese one and even tried to give some rhyme. I agree that the original is weird, therefore the translation couldn't be different.

merci pour vos envois.la traduction turkishmiss s'approche le plus, je crois, du sens général.

Vaccai ( methodo pratico di canto ) avait donné une traduction en anglais ; elle disait : La flamme qui est soumise au vent s'éteint plus facilement. ( En France réponderions à cela : il enfonce des portes ouvertes ...)

Il se peut que ce texte ait été construit artificiellement, non pas sa beauté , mais pour constituer un exercice de vocalise .

rectificatif : il faut lire : non pas en raison de sa beauté, mais
