Deceleration Valve: Description
The deceleration valve is used on all models. Valve is located in the intake manifold or at carburetor throttle plate and is connected by a hose to the throttle valve housing in front of the throttle valve.
The valve is held in place by the clip that secures the crankcase ventilation nipple to the intake manifold. An "O" ring is fitted between the valve and the intake manifold.
