Rusty print the page 6-4 from the shop manual, and the photo I posted in my allbum. Put them next to each other and it should become a little clearer. The arrows in my picture are showing the direction of gas flow, not the direction of rotation, this may be what is cornfusing. I probably could have labeled it differently.

As the bimetal strip warms and expands the spring tension eases and the weight rotates in the counter-clockwise direction closing off the intake and deflecting the gases straight downward and out the exhaust.
Good you got it free p.j., your lucky. That’s 99% or the battle. Now you just have to get the thermostatic spring adjusted. It’s been my experience that they will stay free if you check it at regular intervals and just make sure that its free and isn’t sticking. The problem comes in when it is allowed to stay stuck for a period of time and rust and carbon build up. The oil will burn off, but it won’t hurt to oil it up when it’s cold and work it thru its full rotation every few hundred miles to knock the cobs out.
