internal pressure?

[Steve Northrop]

Yes Pete, it is directly below the reed valves in the valve cover, right 
next to the spark plug recess. It goes through the cylinder head and exits 
in the exhaust port. It's kind of hard to see because the exhaust port is 
always so black, but it's there. The valve between the hoses that attach to 
the reed valve chambers is just a vacuum valve that opens with engine vacuum 
to allow the air to flow from the airbox.
