    Got a problem with a Yanmar 3cyl diesel.
    Runs like it's starving for air but it's not, doggy and blows black smoke under load, no power and seems to get worse as it warms up. Not the air or fuel filter and unit does not have a turbo, also doesn't seem to be missing as if it dropped a cylinder. Shoot me some ideas.....just for the record it's a JD gator

    May have a injector going south. Sounds like its over fueling (black smoke)

    Yeah that's what I'm thinking hoping it's not the pump governor. Got to check the exhaust next, manual recommendation, maybe mice built a nest in it, after that I'll crack injector lines and go from there. Unit is at work, got 6 of these motors, 3 mowers and 3 gators.....all green.
