new to the site and have alda question
unfortunately i don't have one of these awesome little diesels but my buddy just got an 83 300sd, i heard the main adjustment for starters is the alda screw for low boost fueling, so earlier today we started playing with it and i could not get any gains from this i even removed the screw completly and could not get any gains or any extra smoke. why is this? i have herd about mabey cleaning the alda or the banjo bolts going into the pump. any suggestions would be a aprreicated along with other cheap or inexpensive mods.
Yes definitely try cleaning out the ALDA line to manifold, the banjos and make sure the switchover valve on the firewall works (if it is not bypassed). That is most likely the source of your issues.

You need two 27mm wrenches. One to hold the ALDA and the other to unscrew the nut at the base.
well i removed the alda completly and it definatly has a lil better umpff but still doesn't smoke hardly at all and i have checked all the banjo bolts and they are clear and clean, is it just the carachteristic of a ip with 250k on it or is there a problem? is the full load adjustment the next step?
Adjust the full load screw. While you are in there throw out the rack limiter. Then build a customazing propane setup. Don't forget to turn the delivery valve holders. Adjust the transmission to deal with your new power and enjoy.
