Although running well, it appears to be too rich, occassional puffs of black smoke behind me. How can I adjust the fuel to weaken it and see if it cures it?
hi chris as its a diesel you cant adjust mixture as the fuel is injected into the burn chamber and air is sucked in on the induction stroke .most diesels will have the odd puff of black smoke mainly during full thottle at loww revs regards john t i own 4 diesel 405s 2 non turbo
