Full Title

Full titles differ between systems:

IPC:

Carburettors with means for influencing, e.g. enriching or keeping constant, fuel/air ratio of charge under varying conditions > Other installations, with moving parts, for influencing fuel/air ratio, e.g. having valves > with means for controlling cross-sectional area of fuel-metering orifice

CPC:

Carburettors with means for influencing, e.g. enriching or keeping constant, fuel/air ratio of charge under varying conditions (choke valves for starting F02M1/00) > Other installations, with moving parts, for influencing fuel/air ratio, e.g. having valves (F02M7/24 takes precedence) > with means for controlling cross-sectional area of fuel-metering orifice (dependent on air-throttle position F02M7/22)

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
