Fuel pump tweak WTF

Ok the story is my good old RRC has a 200tdi fitted and is way underpowered when setting off. When I got it, it had the 200tdi with the lt77 and lt230 transfer with 1.222 ratio and stock 3.54diffs with 265/75 16 insa tyres, so i was thinking as the motor sounds sweet and seems to pull well when it gets going that it must be due to the taller tyres. So i bought a lt230 with the 1.410 ratio to bring the gearing down to help which it has but if I had a trailer or caravan on i dont think it would set off on a hill without a lot of clutch slipping or sticking it in low. Today i decided to tweak the pump(on top under the cap) 1/4 of a turn at a time but i ended up with it wound in that far the lock nut had nothing to bite on oh and it still didn't kick out and black smoke when setting off so wtf is going on:frusty:

Im now drinking large amounts of larger which i find always helps(short term anyway)

So what exactly have you adjusted on the injection pump?
There are several adjustments.
