RE: Purpose of windsavers?
Mike Curtis gave a good reply to your question - just thought I'd throw in my
1 1/2 cents worth.

Chromatics are leakers - due to their larger reeds, there is more room for the
air to escape around the read. The higher reeds are smaller and don't need
windsavers. (They also leak around the slide/mouthpiece)
When you play a blow note the windsaver (valve) closes on the draw reed which
is in the same hole - thus no air leaks out through the draw reed. When you
draw, the opposite happens - the draw windsaver opens and the blow closes.

Some windsavers are double and are supposed to be separated rather than glued,
or stuck together - Except they are joined at the end where you glue them on
(the rivet end of the reed). That's probably why the whole thing came off.
These two piece WS's are usually found on the lower octave or so. The top is a
stiffener. The idea is to make the WS lay flat and help it seal the leaks on
the larger reeds. The two piece WS can eventually become stuck together from
moisture, etc., making it lay crooked or twisted and causing it to buzz or pop.
(The single piece windsavers can do this too if they get bent, twisted, or
temporarily stuck. They can buzz or pop when they break loose).

Take Mike's advice and put it back on or replace it with a new one.
If you had the mouthpiece / slide assembly off as well and were blowing
directly into the wood, then your harmonica would respond very well - this is
because you are about 1/4 inch closer to the reed.
Of course it depends too on which windsaver you removed. If you removed the one
on the blow reed this would not affect the blow note. If this is the case, try
your draw note - It may / should sound a little weaker.

Hope this clarifies a little bit why the windsavers are there.

P.S. Hi HARP-L folks, I'm back from round II of the flu (I think they're going
to name this virus after me). Anyway, that's why this response is a little out
of date. What? You didn't miss me? Huh? You didn't even know I was gone? -sigh-
Well, back to work - I have 133 HARP-L messages to read - sheer ecstasy!
