Having trouble with that ebay listing on my phone, but that looks like a Mac 15 intake/carb/filter setup to me. For some reason, Mac 15 stuff is often listed with "kart" as a keyword. The carb(s) will be a Tillotson HC. Same as an HL, except gravity fed. No pump section. Saws with high mounted tanks such as the Mac 15, Homelite 500/Buz, and Mono/Wards saws such as my WD 60 had 'em.
Yea Mac 15 carb and intake.
