I have had a 72 300sd and an 82 300d and now an 83 300sd and all of them were extremely slow to take off but once i hit about 20(MPH) I gain speed a little quicker. I have looked at my fuel filters and they are clean but I have been told there is an adjustment that will aid in the speed issue, I am totally unsure what this adjustment looks like or where it is but it sounds alot like what someone referred to as a altitude adjustment earlier. Can someone give me a little more info on this adjustment? Thank you!

dieseldiehard hit the high points... I just turned my ALDA back a turn at a time 'til it felt "right," and fuel consumption didn't change noticeably. Check out the manual before you monkey too much with it, though.... or at least mark the adjusting knob so you know where it was when you started, just in case things get worse.

Good luck!
