    Default 4610 Ford missing won't rev over 1500 rpm

    I have a 4610 ford tractor, 2900 hr that has a cylinder mis like it has a bad injector. However it also won't rev over 1500 rpm. Load or no load. Has steady smoke in the exhaust at all speeds. Idles rough. Piston blowby is reasonable and it starts right up could. Air filter and exhaust seem un restricted.
    I'm thinking injection pump because of low rpm, Just like it is governed at 1500, and needs a injector or valve set. Anyone run into anything like this?

    Sorry I can't help you with this. If you don't get any activity here, start another thread in the New Holland Owner/Operator forum. Should get some response there.

    Are you sure you have adequate fuel flow? The tank strainer could be restricting fuel flow. When was the last time you changed the fuel filter? make sure the connections on the fuel delivery system are tight so you don't suck air.
