The counterweight just pulls the flap closed when little air is 
needed, as at idle, but allows the flap to open when there is 
demand. This provides more vacuum to scavenge crankcase vapors 
at idle, which helps to remove water vapor in the winter.

In the summer you can push the lever over that seam and hold the 
flap open.
