Hello all,
New to this site. I just purchased an 1987 Ford F250 with the 6.9 engine. It has good power, but blows lots of black smoke when accelerating and climbing hills. The truck came from low elevation, I am at about 4,000 ft elevation, and will be using the truck quite a bit at 6,000 to 10,000 ft elevation.
My question is about the fuel adjusting screw. There are excellent instructions here about adjusting it for increased flow. I want to decrease the flow.
This afternoon I turned the screw down (counterclockwise) slightly, like from 12:00 back to 10:00. That did seem to help with the smoking, it smoked less and it was not as dark black.
Can I turn the flow down more, and is there any problems I will run into if I do decrease the fuel flow a bit more?
I am new to this type of diesel, so any information is much appreciated.
