Ford 8000 running rich

I have a Ford 8000 that we use to plant the deer fields and do odd and end stuff around the place. It is not used all the time. When the tractor is running it seems to be putting out a lot more fumes than it did in the past. So bad that it burns your eyes while sitting on it and working. It has normal small fuel leaks for a 1969 model but nothing drips. Not being that familiar with diesel engines and fuel system I am wondering if there is a way to adjust it or is it more involved such as engine wear? Any suggestions would be greatly appreciated.

PS - Happy 4th of July and God Bless America.
 
I would have the injectors checked for drips, and check cylinder compression while they are out.
 
White smoke is typically caused by low compression or retarded injection timing. If I were a betting man, I'd lean towards the latter. More specifically, internal wear in the injection pump.
 
Ck the air filter first in '76 at a dealer we had one so clogged up the tractor would die under load. Took pry bars to remove it. Replaced it all was good just lucky.
 

pin hole in cyl will burn the crapola out of your eyes.

check for bubbles in radiator< when full to the neck< to see the small bubbles of compression getting into the radiator is one check. Not always will work but will most times.
 
"pin hole in cyl will burn the crapola out of your eyes"

That's a new one on me. I've been around literally dozens of pinholed Fords, and not one did that. Steam out the breather tube yes, but not anything more toxic out the stack.
 

yes... everytime I seen a cavitation problem, it would burn the crapola out of your eyes. In the 5 or 6 times I have seen it, its been the common symptom.
 
You must have a different definition of cavitation than I do then. I fail to see how coolant in the combustion chamber is going to make toxic smoke that burns the eyes. Furthermore, most cavitation is so low in the cylinder bore that it never makes it up that far anyway - it usually goes down into the basement.
 
Thanks for all the replies. Wanted to clarify some information to make sure i am giving you all the information i can. Bern had mentioned white smoke earlier. The smoke I see is a dark blue till you put it under a strain and it goes black. Also wanted to add that the tractor still cranks and runs good. Didn't want yall thinking it was a running issue.

I have not had time to do a drip or compression test yet. I am on vacation to the great smokey mountains. When i get back i will work on getting that done.

Again i appreciate all the information and please keep the suggestions coming.
 
I have noticed on some models of fuel injector pumps they discuss a max fuel adjustment. I see several screws on the pump. Does this particular model have an adjustment and if so could you describe where it is located.

The smoke screw is on top at the front. But, always start with the easy stuff. In this case check the air filter. Maybe you have a mud dauber's nest.
