I know, the flap acts as a air restrictor until the engine comes up to
temperature then it opens.  It's more of a engine warm-up aide than a
temperature control thermostat.

The assembly was disabled in both of the type 1's I had and it's disabled in
my Son's type 1. It's a common practice here in the South.

But a true thermostat modulated flapper would be nice up north in the
winter. A friend of mine and I played with a few back home in NY and when it
got really sub-zero cold the engine never did warm up right.

I think the thermostat doesn't move the flaps after
engine warm-up.  It just helps the warm-up happen
faster.

How about an old-fashioned "choke cable" from under
the driver seat to move the flaps?  Do they even
make choke cables anymore?  I put one on my '61 bus
when the Solex choke didn't work right....

I think I have the bug thermostat on my '81.  Is that
NLA, too?
