ABSTRACT:
An adaptor having first and second passages is mounted between a two-barrel carburetor and the first and second inlet openings of a two-section intake manifold, and includes an air port. The second passage and the air port are aligned with the second inlet opening and contain interconnected valves operated by a valve motor, arranged so that when one valve is open the other is closed. The valve motor is operated by a control system including a pair of vacuum switches and a holding circuit, in response to vacuum in the first inlet manifold section. The carburetor throttle arm is equipped with a surge compensator connected to operate simultaneously with the valve motor, to change the length of the throttle arm for eliminating power surges when shifting between split and full engine operation.
