Case 1845b Knocking after replacing seals in injection pump

A while back I lost all power while using my Skid Steer. I took the injection pump off to go through it and I figured I would replace the injectors as they weren't to expensive and I thought that if anything came apart in the pump it may have clogged the injectors. When I took the pump apart I found that the weight retainer rubber had fallen apart. i replaced that as well as the other seals inside, threw everything back together and installed it. I made sure my fuel pump timing marks lined up when the engine was 12 degrees BTDC. I bled the system and confirmed I was getting fuel out of each of the lines just before the injector. I started the skid steer and she fired right up but there is a bad knock coming from cylinder #4 (I think). The smoke is a little white but nothing crazy. The knock sounds like a mis-fire. If I had to guess I would say one of the cylinders isn't getting fuel so I'm thinking its a bad injector. The injectors are new out of the box and the only thing I did was take off the nuts for the stopper so I could get the return line nuts on there. I was careful to count the threads when I took the adjustment nuts off and put them back as close to the same as I possible could. I couldnt find anything on how to adjust those nuts outside of bench testing them and I dont have the resources. Do you guys think I may have screwed something up and the injectors not opening all the way? Is there a general guide for adjusting those nuts or do I need to go get them bench tested and adjusted?

If they are pencil injectors you need to pull all four and have them reset for both opening pressure and needle valve lift. The adjustments must be set on the injector tester, then left alone. You may have one sticking open causing the knock because it's set wrong..
