no bbs ball retainer?

Pics of (some of) (what used to be) my cars are here.

Other stuff I notice: your carb castings look to be in good condition with little or no warp between the main casting and the air horn. Still a good idea to double up on the gasket at that junction (make sure both gaskets you use have all the correct holes in the correct places; there are differences). You're missing the nipple for the choke pull-off hose (maybe it stayed stuck in the end of the hose). You're missing the tension spring on the curb idle speed adjusting screw. Also see here and here.
