1982 Honda CB450SC Nighthawk Dies at Idle?

I recently bought a 1982 Honda CB450SC Nighthawk, and upon purchase, it started up, idled, and ran just fine. The only major issue was a sticky throttle. Since then, I have adjusted the throttle, which now works fine, however the bike will now die at idle. I was told the carbs were cleaned immediately before being sold, and again, it initially started fine.

I have attempted to adjust the idle stop screw, however my battery died on me before I could see any real results. In my research, I have learn there is also an idle mix screw, but I am unaware where it is located on my bike.

If nothing else, I can take it in to my local mechanic, however, if it is something I can take care of myself, I would prefer to. Any other ideas would be appreciated.
