You should not have had to break the washer. I can't remember for sure but it may have been installed upside-down. It is supposed to be there, I have seen it on all the mixture units I have disassembled. I am not sure exactly what it's purpose is but you have to figure the manufacturer would not put extra parts in that weren't necessary. In any case I was correct in that something wasn't right inside and adjusting it was not going to get it. A P.O. or his mechanic must have been in there, this cannot happen by itself, the unit was disassembled at some point in it's history. Now make sure the air sensor plate is still centered. It must not touch the sides of the venturi and the space around should be equal. You may have to readjust the mixture screw, it may be way off if the motor was running with the air sensor plate as out-of-position as it was. That cannot be done except with everything reassembled and the motor running. It is VERY sensitive, ie, a little bit of a turn changes things A LOT. Don't forget to plug the hole over the mixture screw or you have a large vacuum leak.
