    摘要: A carburettor (10; 310) includes a body (14; 314), a throttle valve (26; 326) positioned in an air/fuel passageway (18; 318) in the body, a fuel bowl (30; 330) coupled to the body, a fuel bowl chamber (34; 334) at least partially defined by the fuel bowl, and a one-piece fuel-metering insert (42; 342) coupled to the body. The insert includes an idle circuit passageway (62; 362) having a first end in fluid communication with a fuel passageway in the body and a second end in fluid communication with the fuel bowl chamber (34; 334). The insert also includes a main circuit passageway (66; 366) having a first end in fluid communication with the air/fuel passageway (18; 318) and a second end in fluid communication with the fuel bowl chamber (34; 334).
