The power screw is the front screw that the STOP/START/RUN lever limits against. If your STOP/START/RUN lever is working properly, don't pull the lever all the way to the top of the slot and the lever on the side of the pump will no longer be limiting on the bottom front power screw. That should make the D-179 run a little leaner and clean up some smoke but you need to give it a good hard workout. JimB

Folks,

Thank you so much for taking time and suggest a ways to get it going.

Today I found online that injectors need to have a return line hole pointed toward the valve cover. Mine were pointed toward outside. So I took the #1 injector out and found that it was covered by slimy black mud- looking residue, the entire injector assembly when I pulled it out looked like it was found in a mud and stuck in there. I cleaned it out, then reached in the injector seat with clean rag and wiped all the grime out. The injector body looked like it was subjected to the rust. Since I have no idea of the past of this tractor it is safe to suspect that injectors were messed with . The guy who gave the tractr to me told me that he had injectors rebuilt by some 'friend' of his.

Anyways I cleaned up injectors . Unfortunately I couldnt make a snapshot because didnt want make my camera all greasy and smelling like fuel. Cleaned injectors, put them back on with return line pointed toward valve cover. I didn't think it would make any sense but still, I asembled everything the way it was. Spun tractor over and it fired right up. I loosened up injector nuts some to bleed the air out and tightened everything up. Once engine warmed up I noticed much much less smoke compared to what it was. It still smokes some but I am guessing as some of you suggested once I give it a good workout it should clear up some.

I think I will need to start looking for a replacement injector asemblies to replace my eaten up ones.

I also wanted to run something by you experts out there.. Someone told me today that I should add some transmission fluid to the diesel fuel because he said nowdays the ultra low sulphur fuel that I get from the pump don't have any lubricant in it. Is it sound right ? I am skeptical about that statement. What's your thought?
