Kinda hard to tell from here.. do you have a video you could post?
What fuel system is on that engine.. 3 diff. ones.. got any pictures?
The timing is critical on any of the systems.. are you experienced in inj. pump to engine timing??
How about setting the valves?? is this your first engine rebuild?
"rebuilding" an engine is only half the job..
Not getting the pump or injectors done/checked is like taking a shower & putting on dirty socks & underwear afterwards..
