pd 46 c vent line?
« on: July 08, 2024, 08:08:01 AM »
1978 Honda cb 550k. with PD 46 c carbs.
Where does this black line which I believe is a vent line go to? clear line is fuel line.
I swear it was hooked to something -not just routed out by the swing arm like the float bowl drain hoses.
I have looked at the parts fiche and can't tell. I should have taken more photos before.
Thanks in advance.
