Patent number: 7144000Abstract: An internal combustion engine including a carburetor. The internal combustion engine includes a choke valve disposed within the carburetor, and a choke lever interconnected with the choke valve for movement with the choke valve. The engine also includes a throttle valve disposed within the carburetor and a throttle lever interconnected with the throttle valve for movement therewith. An intermediate lever is disposed between the throttle lever and the choke lever for movement with the choke and throttle levers.

Patent number: 6830023Abstract: An engine starting system that includes a power source, an electromagnetic coil and core, and a choke valve disposed in an air intake of an air/fuel-mixing device of an internal combustion engine. At the time of starting the engine, the power source outputs an electrical signal to an electromagnetic coil and core, inducing a magnetic field from the electromagnetic coil and the core. The magnetic field from the core moves the choke valve toward a substantially closed position that enriches an intake mixture of fuel and air to the engine during starting. In one embodiment, the power source includes a moving magnet that interacts with a stator coil to provide the electrical signal to the electromagnetic coil. In another embodiment, the closing of a starter switch allows a battery to provide the electrical power to the electromagnetic coil.Type: GrantFiled: November 7, 2002Date of Patent: December 14, 2004Assignee: Briggs & Stratton CorporationInventors: Paul A. Tharman, Curtis L. Schultz, Jeffrey C. Blonski, Thomas G. Guntly

Patent number: 6752110Abstract: An engine starting system for an internal combustion engine. The starting system includes a starter switch electrically connected between a battery and a starter motor for the engine, and a choke valve disposed in an air intake of an air/fuel-mixing device for the engine. The choke valve moves in response to a solenoid actuator. The solenoid actuator is electrically connected to the starter motor and a temperature switch. When starting the engine below a threshold temperature, the starter switch and temperature switch close such that the battery powers the starter motor and solenoid actuator. The energized solenoid actuator moves the choke valve to a closed position to enrich the air/fuel mixture. Above a certain threshold temperature, the temperature switch interrupts the power to the solenoid actuator.Type: GrantFiled: September 20, 2002Date of Patent: June 22, 2004Assignee: Briggs & Stratton CorporationInventors: Paul A. Tharman, Curtis L. Schultz, Jeffrey C. Blonski, Thomas G. Guntly

Patent number: 5843345Abstract: An accelerator having a main body defining a main chamber, a movable member (e.g., a diaphragm) positioned within and dividing the main chamber into a pneumatic chamber and a fuel chamber, and a damping orifice (e.g., in the main body) interconnecting the pneumatic chamber with a gas source (e.g., ambient air). The damping orifice has a cross sectional area less than about 0.002 square inches. To inhibit contamination of the accelerator, a filter can be operatively positioned between the pneumatic chamber and the ambient air.Type: GrantFiled: March 14, 1997Date of Patent: December 1, 1998Assignee: Briggs & Stratton CorporationInventor: Thomas G.
