Is anyone here in or around the Tucson/Phoenix (~2500 ft above sea level) area running a cabureted GM 350? I recently swapped carbs and distributors in my ZZ3 and now I am running extremely lean with the factory carb jet sizes (65 primary, 68 secondary). Can anyone recommend a good starting point for jet sizes? I am thinking about starting 5 jet sizes above both primary/secondary......
