This farmer in Nebraska looked me dead in the eye and asked if I could 'make his tractor sound less angry' after I fixed the injector pump.
I was under the hood of his old John Deere 4020, and he just stood there waiting for an answer, completely serious, like I had a volume knob for diesel clatter.
Oh come on, you can't be serious. That knock is the engine telling you something's loose or worn out, not a feature. I had a tractor with a similar noise once, and it turned out the wrist pin was about to let go. It ran "fine" right up until it didn't and cost me a whole rebuild. Your uncle might have been lucky, but that's like saying a rattling exhaust sounds "sporty" right before it falls off.
