Dual arm choke and throttle control

An engine choke and throttle control arrangement of the type in which an operator acutated throttle control handle is linked to a speed governor spring arm and to a choke arm, the arrangement comprising:

• a base plate;
• a first lever pivotally connected to the base plate and including said governor spring arm;
• a second lever pivotally connected to the base plate and including said choke arm;
• a spring extending between said first and second levers;
• a linkage joining the throttle control handle to one of said levers for rotating said one lever about its pivotal connection in response to actuation of the throttle control handle, said spring producing simultaneous rotation of the other of said levers when the engine is operating below a predetermined speed;
• a stop member positioned to engage a detent formed in the first lever when said first lever is rotated to a position at which said predetermined engine speed is reached, one of said stop member and detent being adjustable to establish the position for obtaining said predetermined speed, and said stop member and detent preventing the predetermined speed from being exceeded;
• and
• said spring having a spring force which allows the second lever to rotate about its pivotal connection, independently of the first lever, when the throttle control handle actuation is greater than that required to move the stop member into engagement with the detent, whereby the choke arm is permitted to function when the engine is operating at said predetermined speed.
