OK. Hey thanks for the posts guys. I will go ahead and take the engine apart again. I will remove the rear oring completely, and make sure that there is free movement of the preload system once again. I am sure that the needles were not blocked because I checked them. It is a brand new inconel CC, and EGT's have been well within bounds. When I reassemble the engine, I will run it with the posted settings according to the FADEC manual. y manual must be old, because it doesn’t say anything about this..
Later,
Brandon
Connect the fuel ring and lubrication pipe to gas and check the flame size. Flames from lub pipe should be 2 or 3 times the flame from one needle at the fuel ring but no more. Also check distance from diffuser to combustion camber, should be 6mm. Remember to use silicon to seal the engine, because the oring in the diffuser is not enough.
