Pump Timing

Pump Timing
Turned the pump up 4 flats, had no smoke while loaded, decided to try to gain a bit of power. Had nothing. Went up 2 more flats, all I have is gray brown black smoke, replaced fuel filter, common issue? Still gray, but now even less since the fuel filter... (Not looking for coal, but the girlfriends truck has higher miles, still puts a bit of black out)
113k rebuilt
Injection pump (13k)
Injectors (13k)
No noticeable oil or coolant loss
Compression 340-350
Lift pump (13k)
Always starts within 5-10 seconds of cranking with no glow plugs.
Lack of thermostat wouldn't cause the gray smoke would it?
I'm assuming pump timing... (No access to timing light currently, should I tilt pump?)

Thermostat could because it doesnt warm up. Put one in, you will either wipe the cylinders or overheat it. The fact that you got 6 flats out of it tells me something is weird, never got much more than 3 out of one. Sounds like a wore out pump. Timing wont cause lack of smoke, but should be in the neighborhood of 6-9ish BTDC via pulse adapter.

Honestly, with an old pump like this? adjust it a bit and see what feels the best. You won't be able to time it correctly with a light, because the timing curve will be off.
Just get it where it feels the best/has most power and call it good, while saving up for a new performance pump(chances are your pump is a crummy rebuild?)

Older trucks/pumps(Not sure the exact year, but it was after 88) didn't have a "torque screw". There's no real reason for the screw anyway except emissions, maby.
