The 180 degrees thing is unlikely the problem. If you're geting frothy fuel when bleeding her, there's air getting sucked in. Your plan to retrace all the lines would be my suggestion. The other fellow had a good idea about the separate fuel source as well, to see if she'll go.

When I did my i.p., the standard bleed didn't work at first either. I loosened them all, but not fully. When the fuel came clearly, she actually ran rough. As soon as my buddy tightened them down, she went like a charm. Don't know if that will help you at all, but that was my buddy's suggestion, and it worked. I thought he was full of when he said it, but I ended up losing 5 bucks and gaining a running truck.

 

well, i know i have been asked a couple times, and i did check it but it i must have looked at it rong. it was dark.
well i did my cilicone trick and pulled one and two injector lines. i was getting hardley any fuel. so i checked my full fuel screw, its in for sure. so i checked the indexing. and wow. its off, vertical as looking across the to theother fender.
i am going to start a new thread on how to fix my indexing sence this thread has gotten kinda long.
