#1 rocker rides the underside/side of the cam ("center wheel") like on Cris's. If you bend things in can "sort of" work, but won't be right, might stop, etc... (my brother did it to one)
I mention it because your first pic shows #1 riding the top of the cam.
A pawl IS the one that grabs the teeth. (same on an old e unit drum, different pawl design attacted to a solonoid's ram)
