i thought my trouble getting up hills was down to the trio of 2.88 diff, manual transmission, and large tires, but an ALDA adjustment may have just made all the difference. the engine now sounds heartier and the car comes off the line a good deal more quickly. i left the screw at 1.5 turns CCW but i think 1 turn might have sufficed.

my question is this: what changed over time to necessitate this supposedly unnecessary adjustment? have the aneroid devices in the ALDA itself sagged out of shape? are my injectors dirty enough to have been impeding fuel delivery? what else could have happened in the engine's first 110,000 miles of service that would necessitate tampering beyond the tamperproof cap?
