Does anybody know what is the purpose for the hose that routes on the right side of the carb through a clip on the top of the carb and is left unhooked? :applause:

If im not mistaken it's a vacuum hose.

there is a vacumn hose from air cutoff fitting to the intake manifold nipple with a tee going to the smog pump oem, as well as a top breather hose for the carb overflow that joins a y for the drain ( open to atmosphere).In this pic 25 is breather and 15 is vacumn hose

It's a breather/vent hose. It is routed down through the "O" clip holder and stays pointed down, but open. It's the hose with a harder plastic collar about 1/2 inch long that stops it from being pulled down too tight.
