well after trying to run it yesterday I think that I am through with this engine. It's time for a new one. It would not start to save its life. I have tried going to a hotter glow plug and setting the needles to factory settings with no luck. When at the factory settings I have fuel coming out of the front of the motor. I talked to the lhs owner and he says that there is gonna be a small amount of air leaking at the bearing due to tolerances, and I have a very small amount almost no bubbles at all.
