I know I can just start turning stuff and learn-by-doing, but everything else seems to be shifting great on my 90s Trek 820. It's a 3×7. When shifting from 2nd to 3rd on the front the chain falls off to the outside (right side/pedal side).
Which limit screw do I adjust? The high or low? Do I tighten or loosen?
Thanks bikewrench.

The screw marked “HIGH” is the one that limits travel to the larger, outside ring. It is possible that the derailleur angle (rotation on the seat tube) could be a source of the issue, so make sure it is sitting with the cage in alignment to the chain wheels.
You should make sure those aren’t the recalled cranks.
