Been thinking about this. Say you run a PCV and either want to eliminate it or install a jet to restrict it a bit. How much of a change to the primary jetting is necessary to compensate for the richer mixture? (pcv is a calibrated vacuum leak) I'm assuming that this would only apply to the primary side of the carb, as the secondary should not be affected because the pcv would be closed due to the lack of vacuum, or not affected if the pcv is eliminated all together.
