stano Posted January 21, 2019 Share Posted January 21, 2019 Can anyone tell us what the differences are in 1972 175HP (350), Quadrajet carburators for Non A.I.R. and the California A.I.R. they have two separate carb numbers of 7042202 for non A.I.R, and I think 7042902 for the California A.I.R.. Are the differences of settings and maybe jets or are the castings different. Can a California A.I.R. carburetor be set up with rebuild kit as the same specs as the Non A.I.R. carburetor if we wanted to delete all A.I.R. set up and use the California A,I.R carb for the non smog set up.. thank you stano Quote Link to comment Share on other sites More sharing options...
