Still tinkering with the carbs after the move to a lower elevation. I came from 6300 ft to now 1200 ft. Looking for jet size suggestions. I can hardly make out the size on the existing jets (maybe a 50).
Thanks

Stock on a 65 was 51 primary / 50 secondary.
Per Bob Helt's book, GM went "leaner" on 66 and up - for some reason (emissions in CA?)
