Abstract
A carburetor throttle valve actuation assembly for a combustion engine is readily adapted for use as a remote control actuator, a local control throttle actuator, or both together providing an optional choice for the end user. The carburetor has a throttle valve having a shaft journaled to a body for movement about a rotation axis. A slave lever connects rigidly to a distal end of the shaft projecting outward from the body. A connection spaced radially outward from the axis engages the slave lever to a radially projecting swivel member of a local, manually operated, throttle valve actuation assembly. The swivel member rotates in unison with the slave lever about the axis, is spaced axially outward from the shaft and is journaled to a bracket engaged rigidly to the body. Preferably, the connection has a hole in the slave lever. If the remote throttle control actuator is used, a Bowden wire engages to a pin projecting axially outward from the slave lever at the hole. If the local throttle control actuator is used either a cylindrical void carried by the swivel member mates to the pin, or a peg projecting outward from the swivel member and toward the body is inserted into the hole for…
