Without being in front of your bike. I would say you likely have a fuel issue either your drain screws are stripped or your fuel is leaking from the seal due to a bad float or tang adjustment - clear tube method will allow you to test your foats... that could be causing the drip ...
I have chased down a bunch of little things personally with my bike. Dirty carbs, crappy petcock lack of fuel filter, and faulty ignition system.
Hard to test because you need to test the coils when hot, and at times, it could even give you a false reading.
Are you still running points with mechanical advance? Were you able to confirm all the cyl are firing? What drove me to thinking mine was related to coils, was that 2 of my four cyl were cold when it would run rough... and those two were controlled by the same coil.

Insufficient valve clearances can result in these symptoms.
Cool engine starts and runs okay until it warms up and then runs less okay and won't idle.
Good Fortune!

But Patton has a point. Check your valve clearances.

The other possibilities have been listed: valve clearance is one.
But fuel dripping off the carb makes me think one or more of the carbs needs it's float level adjusted using clear tube method. It's also possible there's a problem with the seal and the float valve so you have some continual flooding or overflow.

It's the same thing depicted in my service manual but seems pretty expensive for what it is at $70. Someone mentioned ebay but I can't find anything. I've never done it before but read the instructions. Alternately I can just get a basic piece of clear tubing, unscrew the drain screw and pop on the clear tube?
About $8
