Abstract
A carburetor with a throttle valve is provided in which a linkage member is in communication with the throttle valve. An idle down handle can be moved from an unactuated position to an actuated position and is in communication with the throttle valve. Movement of the idle down handle to the actuated position causes the throttle valve to be placed into the closed position. When the idle down handle is in the unactuated position the throttle linkage member can cause the throttle valve to be moved back and forth between the open and closed positions.
Claims19
A carburetor, comprising:
- a throttle valve that is movable between an open position and a closed position, wherein a throttle linkage member is in communication with the throttle valve and configured to move the throttle valve between the open position and the closed position;
- and
- an idle down handle that is movable between an unactuated position to an actuated position, wherein the idle down handle is in communication with the throttle valve, wherein movement of the idle down handle from the unactuated position to the actuated position causes the throttle valve to be locked in the closed position so that the throttle linkage member will not function to open the throttle valve when the idle down handle is in the actuated position, wherein when the idle down handle is in the unactuated position the throttle linkage member being capable of moving the throttle valve from the open position to the closed position and being capable of moving the throttle valve from the closed position to the open position.
A carburetor, comprising:
- a throttle valve that can be moved between a throttle valve open position and a throttle valve closed position;
- a choke valve that can be moved between a choke valve open position and a choke valve closed position;
- a choke transmission member in communication with the choke valve;
- a choke handle attached to the choke transmission member, wherein movement of the choke handle causes movement of the choke transmission member that in turn causes movement of the choke valve;
- an idle down handle that can be moved from an unactuated position to an actuated position;
- and
- an idle down transmission shaft in communication with the throttle valve, wherein the idle down handle is attached to the idle down transmission handle such that movement of the idle down handle from the unactuated position to the actuated position causes movement of the idle down transmission shaft that in turn causes movement of the throttle valve from the throttle valve open position to the throttle valve closed position, wherein the idle down transmission shaft surrounds a portion of the choke transmission member.

A carburetor, comprising:
- a throttle valve that is rotatable between an open position and a closed position;
- a revolve bracket that is in communication with the throttle valve;
- a throttle linkage member in communication with the revolve bracket, wherein the throttle linkage member is capable of applying force that is communicated to the revolve bracket to rotate the revolve bracket to cause the throttle valve to rotate from the closed position to the open position;
- and
- a linkage member in communication with the revolve bracket, wherein the linkage member is a portion of an idle down feature, wherein the linkage member has an actuated position in which rotation of the revolve bracket is prevented to prevent rotation of the throttle valve from the closed position to the open position, wherein when the linkage member is in the actuated position force applied by the throttle linkage member to the revolve bracket to rotate the revolve bracket to cause the throttle valve to rotate from the closed position to the open position is insufficient to cause the revolve bracket to rotate to cause the throttle valve to rotate from the closed position to the open position.
