I'm looking for a source for a Q-Jet calibration kit to jet my carb for 5300ft. Any suggestions? What is the carb formula (jets, metering rods, etc) for altitude adjustments? I did find this source, but it is for the Edelbrock Qjet kit. The Rochester Qjet on the car has #7041809 & 3114, apparently a 1971 Chevy carb on a 1966 Buick 425.
Is it an issue of emmisions, running poorly or are you just trying to get some more power or gas mileage out of it? I believe that kit will work on rochester as well, but I have always managed by pirating parts out of other qjet cores.
I'm hoping to improve performance and suspect that the carb is currently set-up for sea level altitude. Seems to be running too rich.
