Holley 1920 missing parts - time to swap?

My son has a 1 bbl holley for sale in parts...

Hmm. Couldn't find the listing when I searched. Oh, maybe it isn't a 1920?

I have a 1967 1920 I'm not using. Rebuild kit installed but it still didn't idle when warm -- I think the idle passages are clogged with old fuel residue. Should be good for all parts as it was off a running car. I need $40 for it to cover my investment in the rebuild kit, shipping & tax. It should fit in a flat rate USPS box for $13.
