Yeah, but that one wire burnt would at worst create a miss either under load, or if totally burned even at idle. I'm pretty sure you've got some type of fuel thing going on. I'd look at any type of dashpot or solenoid that you might have that affects idle related to the AC first, and if nothing there then something that's changed in the carb idle circuit or float level.
