What people will do to extract cash. I'd bet if he hadn't done anything to it, you would probably have a working snorkel. Some people have to meddle.
So frustrating.
Yep, I am betting he purchased it for himself and ruined it with Armour-All before installing on a mower, damaged the end, cut it off, then resold it as "brand new" stock. Either that or a buyer has stuffed it up and then demanded a refund. In hindsight I should have pressed him on the issue of it being shortened. By the time I realized what was wrong with it, too much time had passed.
