This is the problem with generic advice on here. Every machine is a little different, and unless someone has EXACTLY that same machine, it's generic advice. That's why you so often read the advice-"acquire a manual"! Some machines bleed easily, and will run a little air through, some are real buggers and you need to bleed and bleed and bleed.
I don't recall my 655A with in line inj. pump being too bad.
As Rod says, more fuel- gravity helps. It's a matter of logically removing air from the system one step at a time, starting at the supply end. But this is just more generic advice!
