Default Fuel Screw....

If I was to turn up my fuel screw on my 1993 w250 do I also have to do other things or is it fine to just simply .. remove the cap..remove the bolt , turn the screw and put the bolt back on ? ... is that all you do ? thanks ....
NOT because I want it smoking whenever I want it , but because I think it is back off all the way from the previous owner since he towed alot !

I dont know man , I am fairly new to the diesel world ... but after all ive been looking into i think ill leave my trucks fuel pin stock so nothing gets screwed up.....Hopefully you find your problem .. I would just keep playing with it until you find the spot you need it( just remember keep a towel or something in-case in actually does runaway you can throw it on the turbo
