I might have another problem. I'm now running cleaner through it but if I
pull back the throttle under anything but full throttle it drops one cylinder and
it's hard for it to pick it back up unless I give it full throttle and put it under
a load. It will smoke like crazy till it picks up the lost cylinder. If I keep it
full throttle it will run fine all day.

I dont know if your Kubota  has hydraulic lifters  or solid lifters,but from its age I would guess solid(mechanical). If i had the problem  that you are having,I would remove the  valve cover and make certain that each valve had the specified clearance between the rocker arm and the valve stem. If there is too little clearance,a valve may not be closing completely,and without compression,a diesel wont make enough heat to ignite the fuel .  This is what is called "to run the rack",which was mentioned earlier

If its an adjustment issue with the valves, it should run terrible when its cold and improve as the engine warms up, or vice versa, as the engine warms up clearances or the gap in the valve set will change.    Running the rack is pretty simple and fast to do, just pull the valve cover off and take the measurements with a feeler gauge.   

I'd suggest you measure it first before doing anything, jot down the findings so you can look at them to compare what it should be, especially for the cylinder causing you issues, and if the gap is in relation to the other cylinders, or the wear is the same across all cylinders, adjust them to spec and start it up with the cover off, if no change, go from there.

Forgot to ask, does it drop the same cylinder ever time, or has this issue changed cylinders at all since the problem started??

A very fast and simple test for injector, provided the problem has always been on the same cylinder is to switch injectors in holes and see if the problem stays in the same cylinder or follows the injector and go from there.    If it stays with the same cylinder, then its the pump or in the head, if it moves to the cylinder you put the injector, then its certain to be the injector, if that makes sense.   Its a simple way to narrow down the problem, somewhat and really simple and fast to do.   

If this issue has changed cylinders, with no parts being changed or moved, then you have a different set of issues to content with.   

Also have you narrowed down which cylinder is causing the issue yet??

If not when the engine is cold, upon start up, the dead or not firing cylinder won't warm up as fast, and I'd use a heat gun myself, but your hand will work too, touch or point the heat gun on the exhaust manifold and the dead hole will remain colder that the rest, where the exhaust exists the engine.

You can switch injectors pretty fast and I'd do this before pulling the valve cover off to see if the problem moves with the injector or not, if it stays with the same cylinder, then its not the injector, run the rack, if that doesn't solve it, its probably the pump.      Sorry about forgetting to mention this before.   

If the problem has moved all on its own, with no parts being moved or any adjustments being made, that would change things considerably and I'd like to know right away, I'd have to think on that somewhat, its rare but happens, also how many hours have you put on it since this whole ordeal started.

Black smoke from a diesel is partially burned fuel.  Unburned fuel is bluish white and smells like diesel fuel.  As an example; a restricted fuel filter can cause black smoke. Some how the ignition changes timing because less fuel  and the diesel starts smoking black when in fact its not getting enough fuel.  I say, with diesels, forget everything you ever new about gas engines.

Amsoil AMF. Run it 50/50 Deisel. Had a friend with a JD450 running very poorly and almost changed the pump. Sent him my 5 gallon pail of cleaner and it fixed the issue.

I'm late to the discussion but thought I'd share my story.  It's pertinent. 

4 years ago, my 95' International 4700 (DT466) was really losing power up hills and just running poorly.  Long story short, I took it to my local diesel mechanic, who has a reputation in the area as being the best.

He disconnected my fuel tank, hooked up a pressure tank of straight ATF, and ran the truck on it.  I couldn't believe what a difference it made!  Full power restored, and the truck was running unbelievably well right after.  Inexpensive injector cleaning process.

He told me, from then on, to put 2 cans of SeaFoam in every other fillup (50 gallon tank).  I've been using that stuff ever since, and also in my boat (2 stroke), pickup truck, and lawn equipment, and it has made a HUGE difference for me.
