Stop in for a cup of coffee

Hey guys. So. Funny thing. For unknown reason my 408 has developed a acceleration bog off idle. Fully disassembled the carb. Cleaned. I never fine tuned this carb. Has orange cam. And unknown nozzle. Stamped 18. Holly start at 25. Hmmm. Any ideas? Runs great there then that. I did not really notice bog before rust issue...but I really never looked. I was driving pretty easy
