2 barrel Stromberg question

[Dodgerdallas]

Im rebuilding a Stromberg 2 barrel on my 66 318 and theres a small check ball in the kit that shows to go under the pump discharge nozzle-I didnt remove one (which doesnt mean one didnt fall out w/o my knowledge)-and there are a couple of parts in the kit that dont go on this particular carb,does anyone know if this ball goes under the nozzle and I would assume in the hole as thats the only place it would fit??

Sorry about the sideways pics...the nozzle is #13 and the pic thats pointing at the hole is my question,if the check ball goes at all does it go in here?
