650 Diesel Motor not up to Power or Rpms

Posted by migraine on December 30, 2007 at 17:21:30 from (67.182.151.248):

Finally got the 650 Diesel on the dyno yesterday. But it only will turn about 1600-1700 rpms and seems to pop on one injector. I pulled it down several times to try to get it to open up but no avail. It does smoke pretty good even at part throttle and just never seems to really come open. This one sat for over 10 years not running so I cleaned all the fuel lines and tank and put new filters and oil in the pump. Also, when running at higher rpms the fuel pressure guage is at low side when I idle it back the guage goes to operating range. Do you think I have injector or some pump problems? No diesel fuel seems to be getting in the oil or Maybe is the compression lever not completely shutting off the gas Mode? Any help or ideas are appreciated. Thanks Migraine
