Abstract
Abstract A throttle lever for pivoting a carburetor throttle valve is coupled by a yieldable coupling device to normally follow the movement of a throttle linkage operable with an actuating force applied thereto to move the throttle valve towards a full open position. The throttle lever is also connected to a vacuum motor controlled by a solenoid valve to have a normal condition for permitting the throttle valve to be normally controlled through the throttle linkage and, alternatively, a throttle return condition for overcoming the bias of the coupling device and returning the throttle valve to an idle position when the throttle linkage is prevented from normally doing so. Electrically connected with the solenoid is a switch actuatable by a linkage lever comprising a portion of the throttle linkage and having a pivot section. The pivot section is supported by a pivot support so as to be pivotable about a pivot axis and movable laterally thereto to cause the switch to establish the vacuum motor in the normal and throttle return conditions on the respective application and removal of actuating force.
