I have a 17056259 from a 76 Oldsmobile wagon. As some of you may remember this has the 1 year mechanical barometer known as an Aneroid Assembly. I rebuilt it a few years ago but never could find the factory setting for the Aneroid. I specifically sought out this carburetor for my high altitude trips. Found out the hard way it was tampered with when I made a trip from the normal 4XX feet to 4XXX feet and back. After swapping heads I bumped up the jets and maxed out the assembly the other way. I would like to find a specification chart or a base measurement for the needle. Any help from an old wrench would be appreciated.
Thanks,
Thanks,
