Well, I had a feeling that this would happen.

After replacing the fuel lines which was not an easy task of me, I can get the bus to turn over and start, but will not run unless I have my foot heavy on the gas. As soon as I let up, it dies instantly.

Where should I start looking to see what I missed, bumped, disconnected? I had a heck of a time getting the number 1 & 2 injectors back in. I may have switched the 1 & 2 injectors as I was so exhausted I forgot to pay attention to which one was which. That shouldn't make a difference, should it?
Don't worry about switching injectors. Did you pinch off fuel lines and forget to remove the clamp?

That would be like me, but no. I kept an unused clamp in plain sight to remind me to remove the one I had on the line.

I finally got it running roughly enough to get around to the back. RPMs were on the verge of stalling. Timing looks advanced. I turned the air mixture screw in an attempt to just keep it going enough to work on it. About 1/2 turn clockwise smoothed it out a little and brought the RPMs up to 700. is this compensating for an unseen intake leak somewhere?

I don't want to introduce any more variables until I know how to proceed from here logically.

Did you put this back where it was?

I'm not sure. I sort of lost track with all the problems I was creating. Instead, I started with Colin's AFM procedure. I turned the screw all the way in (it went 6 turns) and then backed it out to the mid-point 4 1/2 turns.

I am traveling now, not in my bus :(. I won't get a chance to do anything to it for over a week. Colin will be coming by in early September and I hope he will help me get everything dialed in then.
