'Course this begs the question: Is the valve blocked? Have you tried to pull
air through it, as by sucking on it? If it is, take it apart, dump it in a
small sealed container of lacquer thinner and leave over-night. If this
doesn't clean it, shoot ot full of spray-on oven clean, treat it according to
directions, and rinse with water. Works great.
HOWEVER at least some of the Tiger did come with the connection to the air
cleaner. I remember seeing them that way new............(God, I'm old...)
and I have since seen some untouched cars. AND if not, what's that large
nipple on the bottom of the cleaner base for?
In another vein, blow-by is what the fumes that come out of the filler hole
is caused by and mostly composed of. A new engine with properly sealing
rings, and under no load conditions has little or no blow-by.

PS-The best course for most of us is to pitch the old one in a can to sell to
an originality freak, and to go buy a new one.
