A multiple spindle automatic screw machine is provided with an electrically insulated metal stock feed stop which is connected in an electrical circuit so as to provide an electrical signal when the grounded bar stock makes contact therewith for indicating part count and stock presence.

Automatic metal working machine part counter

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

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.
