Believe you have a 36 but I don't know how similar your engine is as far as physical layout to the 35 120 engine -- but all the springs work the same way -- just a difference in layout. Heat makes them lose tension so as they heat up they loosen and the exhaust force plus gravity on the weight at the other end of the shaft will allow the weight to drop and open the flapper. You want to wind them so when the spring is cold it is wound in the proper direction with enough tension to keep the weight in the up position.
Here is an excerpt from the 35 info showing the spring and if yours has the same relative layout maybe gives enough info so you can see the direction the spring is wound. The photo of the weight end you posted actually looks a lot like the 356 engine and if the other side is similar there is a good illustration of that spring in the 46-50 manual.

Crin, I'll post a sketch tomorrow of the assembly details of your heat riser, it's exactly the same as in my 1100 which I documented years ago when I serviced it.

This old sketch is a little crude but I think it should resolve your questions.
