Unfortunately I don't have a dial indicator and adapter (yet) to set timing the right way, so I have no idea what it's at... I'll probably play around with the timing a little bit today.

More advance will probably clear it up.

It can also have white smoke when warm if air is getting into the fuel.

Air was part of the problem. My first attempt at a cap for the return on injector #4 was a fail. I got that sealed up, and everything is improved. It's still blowing some smoke, and can't get out of its own way. I'm gonna try advancing it a little.

A little update on this thing... I've been driving it for the past few days, and it gets me there and back, but it just isn't right.
I need to buy a dial indicator and adapter and set the timing the right way, but I've always been able to get my 1.6's running better than this one just adjusting by ear/feel. I've replaced all fuel lines in the engine bay. I'd like to replace the rubber lines between the tank and the hard lines... where do you guys find these? I know the supply line is different sizes at each end...
Sometimes the idle hangs REALLY high, and sometimes it barely runs... I might try running some diesel purge through it, but I think it's time to get my hands dirty and open my first pump. The truck is solid enough that I think I'll keep it for a while, and I'm thinking about a re-ring and possibly turbo.

i dont know if i said it before; new fuel&air filters, prime fuel filter from inlet; 1 can of lubromoloy, 1 can of sea foam to about 3/4 tank of fresh fuel; if you have water separator, drain some after a few miles on fuel mix. as far as ear tuning, it can be ok, advance pump to a good/desired point, back off some and see how it goes.

I keep losing my prime. This is a sign that the pump needs to be resealed, yes? Where is the place to buy a seal kit these days?

I was rebuilding a pump last weekend and on Friday. I couldn't get it to squirt out the back end when I was spinning it with a drill.
I ended up tearing it apart, again, and two of the vanes were sticking again. Once I got that fixed I could pump through the pump but the outflow was way to foamy. I knew I had an air leak someplace.
It turned out to be the O-ring on the top of the pump that goes around the governor shaft. A very small nick in it. I replaced it an checked it with the drill and pulling on the throttle did produce spurts of fuel out the back. I slapped 12 volts on the solenoid for that test.
I eventually got it to spin fast enough on the third try of starting to fire up and it is functioning for the most part on the car now. Never would have thought that small nick to make that much of a difference.
It is odd to me that you don't have leakage at the pump with it running. That fluid is under a fair amount of pressure and if you are bleeding air in you'd think diesel would be coming out someplace.

The pump shaft seal is under vacuum when it's running so it's always a prime candidate when air is getting in but fuel isn't leaking out. The other place of course being the injector return lines.

Good info. I'm sure the return lines are good, as they're new, and clear, and I can see what's going on there.

I ordered a seal kit and dial indicator/adapter this morning. And not a minute too soon... it's been doing some weird stuff... revving to the moon on its own, etc. Stuff should be here saturday, so I should be cussing and throwing things on Monday.
