    Frank, I'm wondering how you determined that it's raw fuel coming out the exhaust instead of condensation; i.e., water. I could understand condensation staying in the exhaust system and then slowly evaporating as it warmed at lower RPM vs. condensation being blown out the exhaust at the higher RPM, but I don't know about raw fuel going through the way you described. Of course, by "raw fuel" I'm assuming you're talking about liquid, not smoke.

    In that case, Frank, yes, that sounds to me as if it's using too much fuel. So I'd just recommend you have a mechanic check it out. I'm not familiar with your tractor model, and sure don't claim to be a mechanic, but my first guess would be bad injectors.

    Frank,
    Even if you did have the pump and injectors rebuilt ,it sure sounds like and pump problem or timing problem . I bet that pump is out of time . Call the shop you had rebuild it and ask them . You might even have a broken "flex plate" in the pump which caused my old tractor to run like #$XXX!! By the way , After I got my old pump repaired I ended up cutting the wire lock on the adjustment screw to reset it properly ! The shop had set it up wrong .

    Well ,It sure sounds to me that the pistons are just getting to much fuel injected at one time .Makes me think that it has to be timing or the pump is malfunctioning and unloading to much fuel to the injectors. It very well might be the screw you mention is the problem . I would get a mechanic over to check it out .

    Have the air filters been replaced? Could be right amount of fuel, but not enough air?
