Ignore the settings where it was at. Get it to idle. If it is then gutless, then increase the max fuel. If it starts to hang between shifts or you run out of idle adjustment before you get decent power then jump one spline with the shaft going clockwise and lever going CCW and bring the idle adjustment up until it will idle again. Then adjust the max fuel screw to have more power. Then adjust the idle back down. Etc... After you've done this routine on a few pumps it becomes easy and natural.

I have done this countless amount of times, that is why it is so frustrating lol. I do not feel it is behaving normally.

what return orifice you using if you have the one from the vw etdi pump this would cause the problems you are having ,i think the LR injectors have a 220 bar brake , so you would only need to back off the max screw 1 or 2 turns and wouldbe fine, i am going to fit a landrover tdi pump to one of my 1zs and see how it runs compared to my built Mtdi pump .

I think i am using the one that the LR pump came with for out bolt.
So far it definity runs good. Nice and smooth sounding for sure.

It runs good, but it is not performing good lol. The settings are very sensitive with this one and I am having quite the frustrating time with them... haha
I am having troubles setting a solid idle, and then still having good throttle response with no hanging. If I can get the good idle and not a ton of hang (like I have now) it doesn't feel like its got any balls.. some, but not what I had with the 1.6 DI Franken pump, sadly.

1996 300TDI rover pump, 1998 1.9 AHU pulley and key. Slotted the pump mounts for twisting style pump, fits and times up no problem. All I did was insert the dial gauge first, so I could see where I needed the pulley to be based on cam plate lift. It turned out to be two notches on the belt towards the front of the car from the stock 1.6/1.9/TDI pulleys.. so all in all not a problem to time up. I have it set at 1.2mm and it sounds great, like a big 12.1L I6 Volvo D12.. man do they sound nice.

I don't want to sound like a broken record, but here goes. The following is EXACTLY what you need to do to adjust it.
1. Get it to idle well.
2. If it is gutless at that point, then turn in the max fuel and turn out the idle to bring it back to the same point.
3. If you run out of idle adjustment before you get to a decent power setting, then jumper the shaft to lever orientation so that the shaft moves CW and the lever moves CCW one spline. When you jumper that spline it will initially run like crap. You will then need to turn up the idle to get back to a decent idle setting and it will give you more room in the idle adjustment. You will also have to turn up the max fuel a bunch to get it reasonable, but you end up with A LOT more max fuel adjustment and yet still are able to get an idle setting.
I swear, that's the step by step on how to adjust from the point that you describe. What step is giving difficulty?

i have swaped all the bits from a LR pump in to a nother body to bolt strate on to the vw 1.9tdi , and it only felt 110hp so shimed the gov spring , and changed the small idle spring right at the end to a 1.9 td one its a bit softer , lda mod and cracked in the max screw , it hangs on reves a little but still fine ,and she has good torque now the idle is 700rpm .

Thus the confusion.. Doing all that and then jumping one more spline, without changing anything else, it will still idle... It does not affect it like it has every pump before hand.

What that means to me is that with the jumping of one spline from where it was, the idle spring is not totally relaxed. Great. Just adjust the max fuel in a bunch for the new setting, then set the idle where it needs to be and you're off to the races.

Libby your description has been given a few times here now. I wonder if we should make it a sticky? Seems to be a common problem when we go opening up the pump an tweaking on the parts.
Thanks for writeup DAS

Still giving me a world of troubles.. Clearly something is all tomfoolery. Where i have it right now I have an idle (that fluctuates between too high and stalling intermittently), i have some power (not enough to spin in the rain..) and i have somewhat of a throttle response..
Now following those instructions to a damn T.. This is the best I can get it out of all other combinations. I cannot relax the governor springs (jumper throttle shaft anoher CW) without screwing everything up. Relaxing the throttle does NOT require the max fuel to be turned in at all. I have it so relaxed that there is a ton of free throtle with no affect to the idle.. And turning the max fuel in or out controls the idle fully. Regardless of idle screw position.
This has gotten me on the ground beaten and discouraged. I am losing will to keep trying to get it running.. Lol. No matter what i do i cannot get a solid idle at all. I can move the throttle shaft several positions fromnwhere it is now with no affect to idle.
Furthermore, normally backing off on the throttle arm means more max fuel needed. Not true in this case. It is totally not acting the way it is intended.

What kind of cage does this have in it? Sounds almost like a bad gov mod or gov springs that are nowhere near what it is needed for this engine. Doesn't it,

It has a traditonal style gov cage. Very much the same as the vw one just slightly longer. Bigger springs too. Frig man. I just popped the lod off. Found out my lda was stuck.. So i was gettimg no boost enrichment.. It will most likely go better now!!!
