Couple if questions I have. How long did you let it run for? How cold is it where you are at? What color is the smoke? When my pump came loose on me and dropped down or puked smoke and stumbled all over itself with no power because timing was that far off. I actually ended up snuging the side nut just enough that I could get it to start. Started the truck and slid the pump until it smoothed out and had a nice crisp throttle.

I let it run a minute or two. The smoke was white or black (can't really remember but I think more white). I watched the key go in the gear and checked that it was in the gear before torquing the pump nut down. I am going to pull the oil fill and pull the pump nut to make sure its still lined up. If it is, then I think my 1/4"+ of timing may be the issue. Would lining up the lines as marked on the pump be my best course of action now?

And the leaking KSB...I can just pull that brass plug and replace the seals?

How cold is it where you are? I know if my grids aren't working mine is a smoky rough running pig until it warms up. I'd let it get up to operating temp and see if your smoke and that goes away. It may be you need to fiddle with your pump timing.

It wasn't too cold last night when I started it...maybe 40-50 degrees. Usually my truck ticks right over at anything over 25-30. I can't really gauge what 1/4"+ timing means on my engine. Like how many degrees am I off? I hear of people doing an 1/8th bump. to bring it all the way back down that remaining 1/4" to stock is gonna require loosening all the lines and bending back gently. I just hope that fixes things. My truck had almost zero smoke at cold idle before. Maybe a minute of gently smoking but now it is constant heavy smoking and no power. The KSB couldn't be my smoke issue right?

Loosen the three nuts that hold the pump and see if the pump moves. I was able to move mine a lot without having yo loosen lines. I loosened mine then tightened the one that's easy yo get to. Started the truck and held pump and loosened the one nut enough I could move the pump. I just set it where it idled the smoothest and throttle was the best.

Ok - I'll double check the key. As long as my mirror still shows it square in the gear then I will loosen the pump and try and retard timing as much as possible. Man I hope I can get this thing on the road by Tomorrow - my other truck is currently wayyyyy dead! And I need a truck bad.

Did you make sure the little disc between the camplate and rotor was installed? If it's not it will throw the internal timing, and the pressure way off.

Got it running!

But engine is very knocky and hazes at idle...what could that be?

Timing is off still.

The key is perfectly lined up in the gear. And the lines on the block/pump are perfectly lined up.

Now I didn't take anything apart from the AFC down to the pump body. Could anything have come apart down there? And can I fix that while the pump is on the truck or is it being pulled again?

AFC will have zero affect on the issue.

I got the AFC hooked up again (found a banjo bolt). I dug into the pump only the head side. And only so deep as the cam plate. Is there any way that something like the fulcrum lever or governor pieces could have scattered or fallen out of place? I never took the lid off so I just don't know what could have happened up top.

Nope.


Do you know what I'm referring to about the disc? Between the camplate and rotor?

Yes the little button? I made sure that was in place with a dab of grease.

If timing lines and key are lined up. The only other thing I changed was turning the fuel pin. Does that do anything? Could I need to still retard the pump even further? I just checked and the lines are not 100% lined up but the pump is pushed toward the head approximately as much as the width of one of the lines that are stamped on. Now sure how many degrees that is, but could that have an effect on timing enough to make it sound so different and haze at idle so much?
