Hotchkiss WTF

Had something similar happen to me with a Holley carb during Covid. I bought a 600 CFM, vacuum secondary carb (I'm at work and forget the P/N- 1850, maybe?) for one of my trucks in the Fall of '19 from Summit. Carb showed-up just fine, and I promptly put it on the shelf, thinking I'd get to in the Spring. But then Covid hit, and for various reasons I didn't get to the truck until the Spring of '21, and when I found a broken-off tap inside where the air filter stud is supposed to reside, both Holley and Summit told me I was SOL.

The tap is still there, in fact.....

Learned my lesson.
