If you are installing a used engine, and assuming it has a
conventional Bosh or CAV type fuel system, I would suggest that you
take off the injector pump and all the injectors and have them
tested
and calibrated. My experience is that every time I have done this
the
shop made some repairs to either the pump or the injectors - in
other
words there was something wrong that wasn't noticeable by listening
to the engine run.

SFWIW, my next door neighbor's SIL operated a diesel injector/pump
repair shop.

At least every 2nd year, would make a visit with my Yanmar parts in
hand at the start of the season.

They usually found something.

BTW, Yanmar uses a totally unique system.
