Hi, I have a Mikuni Solex 30-32 feedback carb off my 1987 Dodge Ram 50. It seems the internet is devoid of information on these carbs and that alarms me, because I am rebuilding one.

One thing in particular I need to know is... I was blowing out the passages in the float bowl when suddenly a copper colored spring, ball bearing, the bore's cap (?), and possible more flew out at the speed of light across the shop. Surely I'd never find any of them, but I managed to locate the ball bearing, copper spring and a small rod (related?) but no bore cap.

Specifically, these components:

They seemed to shoot out of this bore (screwdriver pointing to):

I've already consulted the exploded view in the carb kit but it does not note these parts.
Can anyone tell me if anything is missing? What is the correct lineup of parts in the bore? Is there a substitute for the missing cap? I am convinced it is gone forever and none of the junkyards around here have these trucks. Can I just roll without these parts?

Really stuck here, any pointers in the right direction will be sincerely appreciated.
