I have a stock-engined FI '71 Squareback.  I usually get in the mid-twenties
in town(lots of stop and go around here).  I've gotten 31.5 mpg between
Reno and Winnemucca with 800 lbs. of stuff, plus me and the cat.
I learned a lot about what causes bad mileage in the first 6 months
of owning the beast.  Here's some of the things I found:  Misadjusted
pressure sensor(idiot PO had taken the cap off and screwed it in all
the way), misadjusted throttle switch, misadjusted pressure regulator,
timing was out, cracked head, bad valves and last but not least, cracked
and hardened hoses and seals.  But the control box was(and still is)
good.  A gas leak somewhere will also knock the mileage down but you
should be able to find that readily, hopefully before the final bonfire.

The pressure sensor misadjustment knocked the mpg down into the 10-12
range, plugs were black with carbon after 20 miles.  I just replaced
it with an intact one from a wreck.  Mileage went up into the 20s
at that point.
