I posted this in tractor pulling but thought someone here might have one of these.
OK... Here is what I got.
1. 844 cu inch Allis Chlamers 25000 MKII turbo.
2. I rebuilt the motor every thing is tight
3. I rebuilt the injectors and they are set at correct pop psi.
4. I never heard this motor run before I got it.
5. It will start although it takes a shot of ether.
6. It white smokes at idle and doesn"t want to idle very well until it gets hot. Once its hot it will idle nice but still smokes a little.
7. When I throttle it up it black smokes like a super stocker and under load it really pours the black smoke. I can feel it is down on power.
8. I have tried every timing on the pump I can try. Advancing it helps but is still pushing too much fuel.
Can this problem be changed by adjusting the max fuel setting or am I going to have to pull the pump and turn down each barrel?

How much boost do you have? Have you "flow timed" the pump? How was valve protrusion/recession? Have you taken the exhaust manifold off to check which cylinder(s) emit the white smoke?

I am putting a new boost on it now. The turbo is in excellent condition with new plumbing so I doubt it is an issue. By the way The air filters are clean and there is less than 30mmHg of vacum on the air cleaner side. I have not flow timed the pump yet but I am thinking the last person who worked on this injection system was lost. When I took the injectors out all the caps which goes over the set screw were handtight...so they were leaking like a seive. Who knows what they did with the pump??? I do know it was missing the front seal so I put new one on it before I put it back on.
