MS 500i chain running at idle with new clutch

[Lemuel]

I recently replaced a clutch on an MS 500i which had the problem of the chain turning at idle, I removed the clutch which in my opinion had slightly worn springs and I replaced it with a new one, as soon as it was turned on it seemed that the problem had resolved itself but after a couple of accelerations the chain was still running at idle as if the idle was slightly high, I tried to make a couple of cuts but nothing changed; What do you recommend, thanks in advance
