    • A carburetor (10; 118; 122; 126; 262) configured for use with an internal combustion engine includes a body (14; 14a; 14b; 130; 130a) defining a passageway (18; 18a; 18b; 134; 134a) therein, a throttle lever (30; 30a; 30b; 146; 146a) including a cam surface (90; 90a; 90b; 230; 230a), and a throttle valve (26; 26a; 26b; 142; 142a) positioned in the passageway and responsive to movement of the throttle lever. The throttle valve (26; 26a; 26b; 142; 142a) is configured to rotate about a first axis from a wide-open first position to a second position at least 50 degrees from the first position. The carburetor also includes a choke lever (46; 46a; 46b; 162; 162a) including a follower surface (94; 94a; 94b; 236; 236a) configured to be engaged by the cam surface and a choke valve (42; 42a; 42b; 158; 158a) positioned in the passageway and responsive to movement of the choke lever. One of the cam surface (90; 90a; 90b) and the follower surface (94; 94a; 94b; 236; 236a) includes an arcuate segment (98; 98a; 98b; 238; 238a) having a constant radius centered on a second axis. The arcuate segment is sufficiently long such that the throttle valve is configured to move at least 15 degrees while the other of the cam surface and the follower surface engages the arcuate segment.

    • A carburettor includes a primary air passage (19), an adjustable throttle valve (8) situated within the primary air passage, a fuel supply nozzle (28) communicating with the primary air passage and connected to a fuel metering valve for varying the amount of fuel discharged through the nozzle. The fuel metering valve comprises an elongate sleeve (32) movably accommodating an elongate valve member (33). The sleeve and valve member define a fuel inlet space (35). A fuel inlet (37) communicates with the fuel inlet space. A fuel outlet (39) passes through the wall of the sleeve (32) and communicates with the fuel supply nozzle (28). A portion of the outer surface of the valve member (33) is so profiled that the valve member (33) is movable relative to the sleeve (32) such that the area of communication between the fuel inlet space (35) and the outlet (39) varies progressively between a maximum and a minimum value.
