The underside of the arch on the lower side of the rocker should make contact with the lower 8ve cup arm and the rocker should be powered with a flat spring - that will determine which vent opens at any point.
Make sure there's some double action (lost motion) between the LH3 ring key link and the rocker as you gently lower the LH3 ring - that safety double action should be there to be sure the lower vent remains closed while LH3 is off the ring key.
Also be sure the lower end of the rocker doesn't make contact with the joint surface as that too will prevent the lower vent from closing while the 8ve key is held down.
At least your one has adjusting screws on the rocker - mine doesn't, so all adjustments are made by the thickness of the silencing materials used, the thickness of the pads and by bending things to get the adjustments spot on.
