Things get overly complicated when your on hour 19 for the day.... after thinking it over I believe I moved the pump sprocket CCW one tooth initially. I'll check tonight and most likely move it two teeth CW while I am at it. That should get me close to 1.28mm. The Kubvan is not something you want to screw with timing adjustments as it has almost no room to play in.
Thanks again Andrew. I'll set it at around 1.35mm to start. Ideally I would like to find someone with a pulse adapter on the east coast to borrow / rent. The pump piston size, pump cam size, and injector breaking point all change depending on the parts. I was trying above to identify the flywheel tooth location of TDC for the pump cam and BDC for the pump cam. The 12 degrees BTDC should be a datapoint in between on a curve. I'll build a chart for others future reference once I get it figured out. All my parts are new or rebuilt condition so this should be a good one to reference.
Sidebar: If anyone has an AHU ecu and the connectors for the harness they are looking to sell let me know. I could also use the AHU sensors and Vagcom to fine tune.
Do you have the woodruff key in place? (I had to ask) (yes, double and tripple checked that! good point though!When you had the sprocket machined for the larger shaft, was the woodruff key cut in the same place? This is unknown as I bought it "all ready to go" from another member a few years ago.You completely disassembled to pump in order to change the dynamic advance parts. Are you sure you installed the cam plate facing the correct direction? yes, I was like a surgeon pulling this thing apart in the kitchen on the granite with spots marked and laid out in order and orientation... its really hard to screw it up when you do that.The correct timing pin hole is the one that is directly opposite the woodruff key slot. It is not the one that is on the same side as the slot. There should be a timing mark on the inner rim of the sprocket by the teeth. That mark should align with the top center of the pump when the lock pin is in place. Thanks! this was good to know and I did check this, I had it correct.Did you return all of the settings when reassembling the pump? Nope! This was one of the two issues, I had the piston collar screw backed out three turns as I was worried I would over fuel the single turbo setup with the 12mm and 764 injectors. Turns out I had it way to far out. I turned it back into the oem spot for the 12mm pump and BAMB! it started. Are you getting fuel spitting at the injectors? Yes lots of fuel, although, after it started the pump was leaking at the timing advance plate on the front of the pump. Turns out the screws were too loose and fuel was leaking by. It could also have caused some starting issues too.
