I'm going to guess that you are looking at a secondary issue. The metering rod came loose when you took it apart; it's probably not the idle problem you were chasing. The metering rod would cause high speed issues- but it's a Jeep, who knows?

The metering rod provides the transition, cruise and high speed fuel. If the rod fell out it should have been way rich everywhere but full load. Unless the rod fell into the jet closing it, then it would be lean everywhere but idle. It sounds like it was doing its own thing!
