What seems to be the problem with it. Generally the star wheel is turned 4/5 clicks in the anti-clockwise position, and the diaphram has a large step at the bottom. Point the largest point of the step towards the engine.

You may need to adjust it in ver small increments to stop the smoke. I moved mine less than 1/8th of a turn to cure this.

If it has been completely messed up then the best way is to take it off and have it put on a proper flow rig and recalibrated at a Diesel Specialist.  Typically this would be about £100 - £150.

Other wise it's just a case of trail and error....

What are you getting at the moment?? - too much smoke?

Sharpshooter:
Starwheel wise... anti clockwise increases the pre load, so reduces the fuel delivery rate, to get better power you want to be turning it clockwise  :wink:  - which reduces the preload on the diaphragm.
