Hi Keith
It is my understanding that this is called a heat riser valve (i could be
wrong here) and yes it allows heat to rise and warm the intake. There was
one on my Series II as well when I got it and I replaced it for the exact
same reason as you. I do have icing problems with my solex but I don't know
if it is because I don't have the heat riser valve on the new manifold or
not. I'm switching to a Weber so hopefully that will do away with my
problem. I would say change it and see how it goes.

Subject: LRO: Exhaust manifold differences SIIa/SIII?
I'm replacing the cracked manifold on my IIa (okay, cracked is an
understatement - the #4 runner fell off) and the replacement one I have
is
off an SIII. There's quite a difference - the original has a (jammed)
butterfly valve in the exhaust manifold that's apparantly heat
activated,
while this bit is absent on the replacement. What exactly is this for
(heating the carb?), should I be concerned for my Solex and why the
change?
For those of you interested in the progress, my site is being updated
every
few days: http://keith.miata.net/landy . I think it's still a Land Rover
:)
