Abstract: A carburetor includes a main body defining a bore, a main passage and a venturi defined within the bore, and a fuel nozzle carried by the main body and including a fuel nozzle outlet communicating with the venturi. The carburetor may also include a valve member translatable across an axis of the bore, such that in a closed state, the valve member closes the main passage but maintains the venturi at least partially open. The carburetor may also include a needle valve disposed at an end of the fuel nozzle substantially opposite of the fuel nozzle outlet to variably control flow of fuel into a fuel nozzle inlet, and a needle valve transmission may be coupled between a throttle shaft and the needle valve to convert rotation of the throttle shaft to translation of the needle valve.

Abstract: A rotary throttle valve carburetor has a start assist device with an operating member that interacts with a throttle lever of the throttle valve to axially displace the throttle valve, preferably without rotating it. The operating member may be rotated and moved linearly for selective engagement with the throttle lever by any one of a plurality of starting features generally spaced circumferentially about the operating member. Preferably, each starting feature has a face that faces axially outward with respect to the rotary axis and when in contact with the throttle lever. Each face is spaced at a different distance from the operating member axis thus selection of each will cause the operating member to contact and move the throttle lever a different distance. The different distances correspond to varying fuel enrichments that may be associated with different temperatures of an engine to be started.

Abstract: A fuel regulating method and mechanism for a rotary throttle (barrel-type) carburetor which prevents an end-user A/F adjustment that would cause increase in fuel quantity to a level in excess of a regulated value so as to comply with the exhaust gas emissions regulations. A cylindrical throttle valve having a throttle hole is disposed in an air intake passage of the carburetor body 12, the air flow is controlled by rotation of the throttle valve and the fuel flow is controlled by the position of a fuel regulating needle, attached to the throttle valve, relative to a fuel jet port of a fuel supply pipe in the carburetor body due to axial movement of the throttle valve. A bypass passage is provided within the carburetor body to communicate the throttle valve hole and fuel jet area with the air intake passage upstream of the throttle valve. An air flow regulating needle valve in the air passage is operable to adjust the bypass air flow in the air passage to lean the pre-set idle A/F ratio from a maximum rich factory adjustment. The fuel regulating needle valve is sealed to prevent exterior access by the end-user after making the factory adjustment.

Abstract: A number of embodiments of small lightweight outboard motors adapted to be mounted on a watercraft that does not have a transom through a mounting bracket that spans the sides of the hull and is detachably affixed thereto. The outbaord motor is powered by small internal combustion engine that is contained within the lower unit and at least partially submerged beneath the body of water in which the watercraft is operating. Excess cooling of the engine is avoided by circulating at least a portion of the exhaust gases from the exhaust port around the exterior of the internal combustion engine. The engine is powered by a gaseous fuel contained under pressure in a container that is mounted on the mounting portion. Variations in placement and orientation of pressure regulators are disclosed so that fuel pressure will be constant regardless of the trim adjustment of the outboard motor. In addition, the connection between the outboard motor and the mounting bracket is such that the outboard motor may be easily swung from the suspended position in the water to an out-of-the-water position within the hull.
