Topic: 1980 CB650 Custom

I have an '80 CB650C. It has about 440 miles. Everything was fine and then it wouldn't idle at low speed, in fact, if I let go of the throttle the bike will die. It also backfires a bit. This all started after the choke knob vibrated loose. I tightened the knob and the bike never ran good again. Any help out there?

440 miles would be a museum piece,   That low miles the carbs need cleaned.   No idle usually the idle jets are pluged.     Pics of the bike pls

Once running the gaskets will start leaking too.
