I was right...that I wasn't right. Heh heh. Every diesel vehicle that I've owned has had the fuel screw turned by someone, either to the point it didn't smoke much at all, or smoked like a train most of the time. The Isuzu manual, the Robert Bently manual for VW, and any Chilton/Haynes manuals I have read all don't give ANY info on how to set up the pump. I realize it takes proper equipment to get it 100%, but you would think that they could tell you something to at least get it in the same ballpark. Oh well. So all I can do is guess. Until this forum, where there are people that have a clue about this stuff, and it's application to the great Isuzu diesels.

Can anyone confirm that JLemonds comments about removing the cap on the side of the pump, and removing the spring and shim, if it applies to my pump on the 223? Or has tried it? I'm always game for improvements. <img src="/forums/images/graemlins/kewl.gif" alt="" />
