What addjustment do you make to the pump, was it the one on top of the flying souser or inside it ?
The star wheel and rotating the diaphragm mate. If you take the top of the flying saucer (perfectly fine, only air in there no fuel) you will probably see the permanent pen marks on both the edge of the diaphragm and one one of the points on the star wheel.
I didn't touch the smoke screw or max fuel screws.
I left the wastegate on the turbo alone too. Whilst it's common to up the boost a bit on 200Tdi's, it is not recommended on the 300 (although can be done)
PS, is a flying souser a cross between a UFO and a liverpudlian?
@OakwoodTV, that thought about tungstens did cross my mind. I suspect that a lot will be getting dipped in the weld pool as all of us ham fisted amateurs have a go.
