  • Carburetor and method of calibration
    Patent number: 4208358
    Abstract: A carburetor main metering rod is operated by a bracket carried on a vacuum motor or a solenoid armature to control fuel flow through a main fuel passage, and a bleed valve floats on and is operated by the bracket to control air flow to and thus fuel flow through an idle fuel passage. A gage measures the relative position of the bleed valve within an air bleed body to permit proper calibration of the carburetor.

  • Carburetor and method of calibration
    Patent number: 4178332
    Abstract: A carburetor controlled by a pulse width modulated duty cycle operated solenoid has a main metering rod and an idle bleed valve spring biased against a bracket carried by the solenoid armature. The armature is spring biased to a rich position against an adjustable stop and is pulled by the solenoid coil to a lean position against a portion of the solenoid coil assembly. The entire coil assembly is spring biased against a stop which is adjusted to establish the lean position of the metering rod and bleed valve.
