Just got done ajusting the alda on the beater 300SD, thanks to the helful advice here, didn't want to get into it until I checked other stuff like the valves and timing, and man, could not the believe the change in acceleration. Used to have to be very patient waiting for a big enough gap in traffic to pull out, so it's pretty pleasant to be able to actually get out of the way when someones rolling up on you too fast. So far I'm up to 3/4 turn ccw, might try a little more, but don't want to push it without an EGT guage....So if you have tried everything else and your car is still a dog off the line, try it, you might like it...but maybe have a backup car incase something breaks internally.
