Wanna see what winning the lottery looks like?

I had a Carter 500 4bbl on my 65 dart gt sl6 4spd car. I was driving it home from a job, and the idle kept increasing like it was stuck on the fast idle cam. I kept trying to kick it down off of the cam, but it wasn't really working. Finally pulled overy at my mother in law's house to take a look and found that the screws for the throttle plates, which are supposed to be swedge- locked in, were MIA, and the plates were working their way out of the slots in the throttle shafts and holding the engine at a faster and faster idle. I bought that carb brand new, and had been driving it for at least a year. I don't know where those screws ended up, just know they disappeared. I called Carter and they said I was crazy that could never happen. I think Carter disappeared shortly after that.
