    Abstract: A carburetor including a body having a main bore through which a fuel and air mixture is discharged from the carburetor for use by an engine a priming passage communicated with the main bore, a pump that moves fluid into the priming passage, and a flow restrictor received within at least a portion of the priming passage to reduce the minimum effective flow area of the priming passage. The flow restrictor has a body received at least partially within the priming passage so that fluid flows around the flow restrictor and between the structure defining the priming passage and the flow restrictor.

    Abstract: In at least one implementation a carburetor includes an intake bore with a port opening into the intake bore, a fuel chamber from which fuel is supplied to the intake bore, and an accelerator device including a fuel reservoir. A fuel flow control valve is provided between the fuel chamber and the port to control the flow rate of fuel to the port and at least one passage communicates the fuel reservoir with the port and fuel in the fuel reservoir is supplied to the port therethrough. The passage also communicates the fuel reservoir with the fuel chamber. The fuel flow control valve is located between the fuel reservoir and the port and between the fuel chamber and the port, and the passage includes a portion extending between the fuel reservoir and the fuel chamber independently of the fuel flow control valve.

    Abstract: In at least some implementations a carburetor may include a main bore through which a fuel and air mixture is delivered from the carburetor, a fuel metering assembly, a supplemental fuel pump and a valve. The supplemental fuel pump includes a diaphragm that defines a fuel chamber on one side from which fuel may be discharged to at least temporarily increase the amount of fuel discharged from the carburetor and a reference chamber on the other side that is communicated with a reference pressure source. The valve is electrically actuated and moveable between first and second positions to at least substantially prevent communication of the reference pressure source with the supplemental fuel pump diaphragm when the valve is in its second position to thereby inhibit or prevent fuel being discharged from the fuel chamber.

    Abstract: This invention provides a low cost, easily installed means of supplying supplemental fuel to an engine for the purpose of cold starting and enrichment, which also functions as a means for manual operator adjustment of low speed fuel flow. This system is easily adjusted by the operator while driving, requiring only one adjustment for a multi-cylinder engine. This system reduces the fuel delivery imbalance caused by the phase relationships of the fuel pressure pulses and the pressure pulses existing at the outlets of its fuel delivery orifices by using orifices of different areas.

    Abstract: The invention provides an inexpensive acceleration apparatus of a carburetor which can stably supply a fuel for acceleration for a long time. In the acceleration apparatus of the carburetor, a cam lever (8) provided with a cam surface (8A) is fixed to a throttle valve operating shaft (4A) disposed between a throttle lever (5) and an end portion (3A) of a supporting boss (3). A first lever (10) is brought into contact with the cam surface (8A) of the cam lever by a first spring (12) for urging in a first rotational direction (A). A second lever (11) is brought into contact with a restriction portion (10C) of the first lever (10) by a second spring (13) for urging in a second rotational direction (B), and is arranged in such a manner as to be brought into contact with a pump rod (6H) for pressing a pump diaphragm (7) of a pump apparatus (P). A contact portion (K) of the first lever (10) brought into contact with the cam surface (8A) of the cam lever (8) is arranged between the throttle lever (5) and the end portion (3A) of the supporting boss (3) in a direction of a longitudinal axis (Y—Y) of the throttle valve operating shaft (4) and within a projected plane of the throttle lever (5) on a surface perpendicular to the longitudinal axis (Y—Y) of the throttle valve operating shaft (4).
