  • Fuel metering rod positioning means
    Patent number: 3953549
    Abstract: In a carburetor having a fuel metering rod longitudinally movable through a fuel supply orifice with a lower end laterally movable to a limited degree, a positioning link connected to the lower end positions the metering rod according to fuel demand. An adjusting lever is pivotable with respect to the housing and includes an adjusting screw to set its position. An adjusting link connecting the adjusting lever to the lower end of the metering rod causes the position of the metering rod to be changed independently of fuel demand according to the position of the adjusting screw and lever.
