A quick background on what has been done: the IP is used, so I have no good history on it. In order to start, I have to step on the pedal a bit and treat it like a farm tractor in that respect. It has good power, but it smokes black smoke real easy. It is starting good each time if I hold the pedal down a bit, 1/4 or so, not floored or anything.

One other thing, the fuel is old too, as it took me quite a while to get time to mess with it. A friend was using it, and his uncle tried to help by pulling the IP off. To someone who has never touched these, what looks like the easiest way? Yep, took the housing off. Got all that timed up again, and that pump just barely had any power to it, so tried the original pump again, wouldn't prime. (Truck had died on the road is the original issue.) I had this other pump that came off a truck that was getting crushed so I went after the easy and quick stuff and grabbed the IP. Sad, as the motor was supposed to be good, and the truck itself really wasn't that bad of shape. Anyway, I put that IP on and now it resembles its former glory except the extra smoke. I am guessing I should try turning the fuel screw down, but want to cover my bases before I go there. Could it simply be I need to bump the timing up a little? I don't know as I can get much out of it now, but can certainly give it a try. Thanks!

 

It would be good to put a meter on it to make sure it is timed correctly but it sounds like you need a little less fuel (or more air) It is quite possible that the person who had the truck out of the junkyard had turned up the IP a bit.

 

I would say adjust the timing a bit. When cold, it should clatter a bit, and when it warms up(and the HPCA solenoid turns off) the clatter should calm down.
Also, if you have very little power when cold, which comes back when warm? You're too advanced.

Once you've adjusted things to where you get the most power/feel the most responsive, turn down your fuel. Or, get a turbo! >:3

 

I have the turbo, just trying to iron things out before I go to that point..

Come to think of it, the clatter isn't as loud at cold as I remember. It initially tried to die at first when cold to. Guess I see if I can get a little more out of it... it does have good power right out of the gate though.

 

you don't want it rolling coal easily without a pyro.be careful,if you don't dial her back a bit.

 

check to see if the cold idle advance is working. it is very easy to knock the plug off the sensor under the alternator.

 

I am pretty sure that is not working. It has no fast idle.

 

My 7.3 did that when I first installed it. The PO did tell me he had maxed out the fuel on the IP. I backed it off a couple of flats problem solved.

 

Did you check the simple stuff like a restricted/dirty air filter?

 

Yes, I stay on top of that, while other members of my family, not so much... I also have a cold air induction from behind the grille.
