4500 injector timing mark

I made a bad mistake , when I checked the timing marks before removing the injector . It was getting dark and I just used a narrow wire brush to clean enough to see the two marks were lined up . When I got ready to reinstall the pump I cleaned the area off more and found there was a scale on the timing cover not just a single mark .There is a scale in 2 deg increments with zero in the center and 12 degrees above and below the zero . Now I don't know which mark it was on . I can tell fairly close by I can see marks where the flat washers on the mounting screws were against the injector slots . I could tell a lot closer if the washers had remained flat but they sort of sank down in the slot on the flanges. I believe I have it within 2 deg plus or minus.Where I have it is 2 deg below the zero. I didn't get everything bleed today . Is there any way to time that closer ? Will it start 2 deg off ? If so I might could move it a little to where it runs the best . But it might spin in the slots and mess up good to loosen the bolts will its running .
 
YES, it will start at 2* but most are at the 0* mark..
It just depends on the amount of gear train wear you have..
It might start easier at the 0* mark.. or not..
You didn't mess up..
 
Thanks so much for replies , the mark on the injector has OK stamped over it. I was glad to hear the 0 is the usual setting . 0 is probable where it was . The injector has been off before because who ever did it used a different bolt on one of the drive hub to timing gear bolts . They also somehow removed the line up pin from the timing gear .I was afraid to try to put one in for fear of dropping it in the timing cover . I was lucky the engine just happened to stop with the line up pin hole facing directly away from me toward the engine . I could see the grove on the injector and the pin hole were together . I had also turned the pump so it would be close to right before I installed it and I had a 1/4 x 4 bold pushed thru one of the timing bolt holes that I could let go thru the matching hole in the pump flange as it slide in place . This forum is great , I don't know how I kept the tractor running all those years before the internet was well established . The old shop mechanics would not tell you anything much except " You will just have to bring it in to the shop for us to check it out ". I didn't blame them really , in a small town that is where their bread and butter came from .
