Engine goes right to full throttle/advance

I once had a ford 2.3 pinto that I dropped the air cleaner wing nut into the carb and down she went. I think it got past the valve because it knocked like a son-of-***** for about an hour straight. I was afraid to turn it off because I didn't think it would start again. It finally got quieter and quieter until it was gone. I thnk it actually relined one of the cylinders:) I ran it another two years with no issues. Even ran smoother......go figure.
