This is the Evolution 116GX2 116cc Twin Cylinder 2-Stroke Gas Engine. The 116GX2’s innovative CON-JET™ induction system actually adjusts the mixture as the throttle is opened and closed. Mixture is leaned with the throttle body in the low rpm position for super-smooth idle performance. As the throttle is advanced, CON-JET richens the mixture to give the 116GX2 superior acceleration into the upper power range. Also part of the CON-JET system is a dual-channel intake manifold that guarantees both cylinders get the exact same fuel/air ratio from the big-barrel Walbro carb. The result is optimum power production and uniform cylinder temps flight after flight. If you’re looking for unlimited power potential for giant IMAC machines or huge scale replicas, nothing else comes close.
