Thanks for the information. I put WD 40 on the heat valve shaft and after some manual working, it freed up nicely. With the engine at about 100F, the spring can just raise the weight to the up position.

I'm going to leave it alone as long as it opens fully when hot, at least until cold weather.I suspect that on a cold morning, it would hold the heat valve closed firmly.
