Abstract
A carburetor including a main body and a throttle valve received in a mixing passage through the main body. The throttle valve is movable to adjust the quantity of a fuel and air mixture supplied to an engine. A carrier member on the main body has a threaded bore in which a shank of an idle speed adjustment screw is received to adjust and control the idle position of the throttle valve. The idle speed adjustment screw is formed of a polymeric material such that the shank is deformed by engagement with the threaded bore to reliably retain the idle speed adjustment screw in its adjusted position in the threaded bore.
