I have seen posts asking for info on the inline A pump

I take no credit for it, the article was done by nevrenufhp
To the rear of the pump on the top is 2 different allen plugs. The bigger one is the fuel rate, and the smaller is the star wheel, or pre-boost smoke adjustment.To do the fuel you take off the plug with either a 3/8" or 10 mm allen wrench. Now tie up the fuel shutoff sol. or pull cable in the run position and you will see the adjustment screw. You may need to put a brick or such on the accelerator to keep the screw in the right spot under the hole. Break the jamb nut loose with a 3/8" or 10 mm deep socket and loosen the screw all the way. At this point it will be loose in the rack, but not fall in. Take some needle nose pliers, or magnet retrieval tool and carefully remove the screw. Run the nut so there's 3-5 threads left on the screw(away from the head). Now (again-carefully) put the screw back in and tighten it with a regular slotted screwdriver up to the jamb nut. Then a good snug on the jamb nut and it's done. Note #1: if you get the screw too high, it'll hit the top of the pump and make the rpm stick. Run the accelerator and check to see that it wont bind up in there. Note #2: If you drop the screw inside the pump you can retrieve it easily with a pencil type magnet, and it's not that easy to get out. Untie the shutdown sol. and remove the accelerator weight tool. Under the smaller allen plug is the star wheel. Take the plug off with either a 5/16" or 8mm allen wrench. Spin the star wheel towards the front of the pump(rotate towards the pass side) to increase low end power(smoke)and away for less low end smoke(essentially releasing the tension on the spring inside). The governor spring mods, and accelerator stop screw are the same as the newer 466's described above. The timing advance is covered in the same article as mentioned above or here it is again: http://www.thedieselgarage.com/forums/showthread.php?p=235958#post235958
If someone out there is a brave enough person, try running withouth the fuel screw. I havent tried it, nor can confirm it wont cause pump/governer damage. I know some Cummins 6BT owners run with no fuel plate, that's why I thought of the no-screw on these.
