its fully loaded at the moment, and you can see the catch holding the linkage back. So right now in order to fire it would rotate clockwise till the sprocket pivot point goes under the linkage, therefore passing center and allowing it to swing free.

The aluminum bolted to the sprocket is just to give the linkage a flat plane to slide on.
