1983 300d rough idle, no power

I have a 1983 300d with 155k miles on the engine. I have a rough idle issue and no power on take off. slow as a old dog. I have replaced all diesel filters. in tank screen also. I replaced motor mounts and shocks. performed diesel purge, got lil better, but still same issue. Performed valve adjustment, checked cam lobes, ok. performed cold compression test, found 410 to 405 on 1,2,3,4 and 5 cylinders. replaced glow plugs and relay.checked turbo alda, correct and functioning. checked for blockage, found clean and clear. I really dont know what else can be causing this issue. HELP!
