Check the tags on the carbs. For '70, C3292LH/RH are non-adjustable,
C3365LH/RH are adjustable, supposedly. The easiest way to check is to remove
the dashpots (carefully), empty the oil out, and peer up the damper tubes to
see if there's a allen-key hole at the bottom.

Well, I think they're supposed to compensate for increased air-leakage
past other things, like the butterfly bushes. Turning them in allows less
air past (since the bushes are allowing more). In some of the later emmisions
plates they're listed as "idle mixture screws". Note that they have little
impact above idle.
