  • Patent number: 5069180
    Abstract: An automatic choke apparatus is provided having a choke plate mounted for variable rotation in a carburetor between a closed position and an open position wherein a flow of air entering the carburetor is substantially obstructed in the closed position compared to the open position whereby the flow of fuel entering the engine is increased when in the closed position. The choke plate has a choke shaft arm for rotatably moving the choke plate. The automatic choke apparatus has a throttle plate downstream from the choke plate mounted for variable rotation in the carburetor between an open position wherein a flow of air and fuel mixture exiting the carburetor is at a maximum and a closed position wherein the flow of air and fuel mixture exiting the carburetor is at a minimum. The throttle plate has a throttle lever for rotatably miving the throttle plate.

  • Patent number: 4528966
    Abstract: A liquid propane gas fuel system includes a propane fuel tank. A two stage pressure regulator defined by a housing with a fuel inlet and a fuel outlet is also included. A first fuel conduit extends from an outlet in the fuel tank to the fuel inlet in the pressure regulator. The system supplies fuel to an engine that includes an exhaust gas manifold. A thermoconductive mounting bracket is secured to the housing of the pressure regulator and manifold to transmit heat from the manifold to the regulator in proportion to the load imposed on the engine. A chokeless carburetor is also included in the system and is in fluid communication through a second fuel conduit with the outlet of the pressure regulator. In an alternative embodiment, a heat exchanger is included in the first fuel conduit. In a second alternative embodiment, an electric heating element is positioned within the housing of the pressure regulator.
