Altering the float-chamber pressure (enriching the fuel-air mixture during starting by depressing float to flood carburettor F02M1/18)

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 > Altering the float-chamber pressure

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) > Altering the float-chamber pressure (enriching the fuel-air mixture during starting by depressing float to flood carburettor F02M1/18)
