They were missing in the carbs I bought...

have you any idea what size emulsion tubes should be in the carbs? i have some but im not sure what the number on them is.

I have a set of F16 emulsion tubes.

I need the little brass parts with the screw slot in them that retain the main jet stacks.

Part #10 on here:
