mystery part inside the engine

[jjefferson]

So doing a quick and dirty valve / ring job on the old plow truck and found this in the #1 cylinder intake valve, wedged down low around the valve guide. This is a 54 M37 with a transplanted 57 Plymouth Belvedere engine.

It’s the same size of a quarter with a small hole in center. Kind of reminds me of the blank slugs that were used to trick pinball /video game machines, but it has more heft to it. The center hole looks to have a wear mark where small fastener head was.

I tore the carburetor apart about a year ago (Carter BB) - but I don't recall this matching anything - of course that was a year ago, and things are kind of fuzzy from last year.

Anybody recognize what this is / was? It looks familiar but I can't figure out why.

Thanks-
Jim

Solved it -
I have solved my own puzzle. Just went through my pictures from rebuilding the carb last year. And voila.

Not sure the proper term - but it is the little disc on the choke plate. And it was missing from the carburetor when I rebuilt it last winter. As I recall I pulled one from the spare parts bin. Of course now I will have to double check and figure out what I did last winter.

Wonder what happened to the little screw that held the disc to the choke.

That is an incredible series of photographs! I have always pondered how well an engine would inhale small parts like that. It seems you were pretty lucky, all things considered.

Please write to me at the contact us link below. I would like to correspond with you about using high res versions of those images in the magazine, if you have them available and are willing.

Hey Gordon
Be happy to send you some photos.

My camera is one of those waterproof Olympus models from Costgo. Takes really good pictures and its waterproof which is great for working in Alaska.
Of course most of my Alaskan pictures are shots of the radar screen and work pictures.

Thank you!
