How Could I Be So Stupid/Careless?

Similar to post 4, I used a ss washer and nut on my air cleaner, picked it off the carb and the washer went to parts unknown. I searched all over for that washer and come to the conclusion that it made it`s way in the carb.:BangHead:
Tore the intake off no luck. I figured I better pull the heads too. no washer.:wtf:
New gaskets and reassemble.
Years later I bought new heads for it and found that washer in a deep crevasse of the Dside header:lol: One of them better safe that sorry scenarios.
