Well, thanks to Volfandt's easy to read, detailed post,
I finally see the "light".
In the cold position, the flapper counter weight has its rounded side up.
In this position the flapper is "open" to the intake manifold,
and redirects some of the exhaust gases to heat the mixture.
Open & Closed was the issue for me........
Since the flapper is located in the exhaust manifold,
I thought it was opening & closing the exhaust manifold.
But instead it's referring to opening & closing off the intake manifold.
That's how I got it bass ackwards.
Thanks for clearing this up.
I'm just glad the old "flapper girl" is still working....
she is quite a gal and her rounded side is always up when she is cold.
