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.
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.
