LN61 2LT rough starting

[shroom]

Hi all,
My truck seems to be getting a bit worse at starting in the mornings.
Basically what happens, is when its been sitting over night, or for a longer perioud of time than around 8 hours, and i go to start it up- its rough as guts.
It will blow a large plume of black/grey smoke out the back and it feels like its not running properly on all 4 cylinders.
By this, i mean it is firing on all four, but one or two feel like they dont get enough fuel or something.
After giving it a rev, it comes fine and will run ok.

Am going to go get a compression tester today and new filters etc.
Injector pump is timed properly...

Any ideas?

Check the glow plugs, had the same trouble some months ago and replaced the glow plugs all good.
