did you set the pump timing? Did you set the pump timing with the advance knob pushed in?

n00b!!

nope, put it on at about the same spot as the previous pump and its been running pretty well its just super rich

i got a good friend with all the tools to set the timing, should i just go up an have him set it all for me?

A rich diesel just revs up. I'd say timing is off, probably retarded.

yup, same case as I.
you get unburnt fuel from the exhaust no matter how low the rpm right?
you can have air in the IP, a leak somewhere or timing issues.

or all of the above

I'll place a vote for retarted timing as well.

no just on hard accel, an if i open er up all the way it just pours black smoke out, it def makes cars dissapear! haha

it runs great, starts up perfect, but i only need to pull the lever out about half way for just a few min in the morning. it smoke a little bit right off idle an then if i stay in it, it starts pouring black smoke, i cant hit full throttle cause its black way before that haha
