Thanks Dan! I'll take a look at your links. I'm going to install the spring again and hold the heat gun on it a little longer to see if it moves. My concern started after my test drives. I saw that there was a little gas leak on/around the carburetor. Also, I thought I could hear the gas bubbling or boiling in the carburetor? Same after the second test drive, so I put some gloves on and reached under the intake manifold to check the orientation of the flapper. It was open allowing additional heat to the bottom of the carburetor. At 90 degrees that day, I thought this flapper should be fully closed. I did order a new spring, but if this current spring does not close the flapper, I'll try to install it so that it keeps the flapper closed for now.

Otto - Yes, flapper moves freely - no resistance at all. The attached picture is not my flapper, but the weighted end sits like this when flapper is open and then the top spins towards the engine to close.
