To me, it sounds like you modified the carb(s) for a cam you are no longer using. That means your combination is no longer calibrated. I would reconnect the vacuum advance, and re-check vacuum. Should be 16-20" at idle depending on what cam you have. Much less if a large cam is being used. Stinging eyes and stink IS unburned fuel....either by misfire (ignition) or just waaaay too rich. If it's not misfiring, it's too rich. My bet is that the carbs need to be put back to stock ;for a baseline and you can go from there. My '65 GTO stinks at idle too...it's due to a large, antique SIg Erson Cam that's in place. No misfire....just too much fuel at idle. I try not to idle it much!!
