Seems to be a bit draggy on the downstroke. I have long wondered how well balanced engine-driven pumps need to be. Apparently it's not critical. Near where I live there are some electric ones. Those are Definitely pretty well balanced. One of the most attractive industrial sounds is the whine of a 3 phase motor.
Very clean, but hard working Arrow 👍🏻
I really like that they still use them today.
