Some diesels (and some electronic petrol engines) have very fierce idle speed governors. As the clutch is eased the governor will crank on the fuel attempting to maintain the set idle speed.

Detroit diesels eg 6V92 used in coaches had this type of governor. The standard way to move off was zero throttle, ease out the clutch and when fully engaged squeeze down on the throttle. This even worked up hill. Good for the clutch also.

My Barina SRI was similar but the fly by wire throttle was a bit too slow.

I have no idea about the diesels you are comparing but the way the governor works may be at play.

Love those Detroit 2 strokes!!
Yeah that's what I'm wondering may well be wrong with the poor performance Isuzu motors I mentioned, the pump could be adjusted wrong, or simply worn....
