Could I add that in 1975, Cadillac started the year out with an
altitude
compensated Q-Jet. It was very complicated, with two power
pistons.
three metering rods, and an aneroid-controlled jet. In the
middle of
the year, probably when they came out with EFI, they switched
back
to a standard Q-Jet. Then, in 1976-7-8, they re-introduced the
aneroid as an "altitude option". I have both of the 75 model
carbs,
and I ran out of patience screwing with the trick one. JWID
