Abstract: A needle valve body (220) has a needle hollow part (230) and a slit (232) extending in an axial direction and opened forward in a tip region. The carburetor body (B) has a body hole (202) receiving the needle valve body (220) in a longitudinally displaceable manner along an axis and a step-part circumferential edge (240a) formed in the body hole (202) and forming an orifice (250) with the slit (232) of the needle valve body (220). By operating the needle valve body (220) to adjust the size of the orifice (250), an amount of fuel supplied to a fuel discharge part (Fout) can be adjusted.

Abstract: A two-cycle engine having forward scavenging is provided. Mixture drawn into the crankcase via a butterfly valve carburetor is conveyed into a combustion chamber via transfer channels in the cylinder. An air duct is connected via a controllable connection with a transfer channel to supply essentially fuel-free air thereto during a load state of the engine. To convey a fuel quantity adapted to drawn-in air during idling and partial load, yet during full throttle to achieve separated supply of air and mixture, a dividing wall extends in the direction of flow of air in the carburetor intake duct. In the pivot region of the butterfly valve, a connecting aperture in the dividing wall is closed in full throttle by a completely open butterfly valve. During idling and partial load the connecting aperture is open so that a uniform pressure can form in the intake duct in conformity with drawn-in air.

Abstract: A method of making a carburetor by first extruding a length of material and then cutting a carburetor body of predetermined length from the extrusion. The extrusion includes a passageway. A venturi member is molded of plastic material and inserted in the passageway. A fuel bowl is molded from plastic material and is secured to the body by means of a resilient clip.

Abstract: A carburettor for an internal combustion engine is provided with a porous material of very fine porosity of less than 12.mu. at a part or parts where a difference in pressure is developed within the carburettor from a relatively low pressure to a relatively high pressure in the direction of the air-fuel stream by a displacement of linear flow of the air-fuel stream.

Abstract: A carburetor including a one piece choke valve and shaft assembly including a shaft, a detent plate formed on a first end, a lever arm formed on a second end, a pair of opposing collars formed adjacent the detent plate and lever arm, a valve plate centrally positioned on the shaft, and opposing splines formed on the shaft enabling it to be inserted through an assembly slot cut into a shaft bore in the carburetor body. The detent plate includes a partial annular slot encompassing the angular range of travel of the choke valve. First, second and third detent pockets are formed along an outer edge of the slot. A positive positioning pin engages or interacts with the detent plate to positively position the choke valve in first, second or third angular positions corresponding to “close choke”, “half choke” and “open choke.”
