HEAT RISER / CONTROL VALVE
Gas is still percolating in the carburetor, and I was percolating too last night when the car flooded from it and died about 5 times.
I did a big write up on page 99 of this thread about how I think the heat control valve works, but even I don't have the patience to walk through it again.

Now I suspect I have the parts in their backwards, reversed, which I've done on several other components in the past before getting help or figuring it out.

I JUST NEED TO KNOW THE ANSWER TO ONE QUESTION, if you have a 356 engine, looking from the REAR of the manifold hot box, with the engine on your left:

Does the COLD heat control valve shaft START OUT turned as far as it can go CLOCKWISE and then move slowly counter-clockwise, rotated by the spring and counterweight, as it warms up?

Or does it start out COLD turned as far as it can go COUNTER-CLOCKWISE and gradually turn clockwise as it warms up, again, from the perspective of the rear of the manifold hot box?

Please
