Welcome Jeff, how did you prep to run after the nap? You run compression checks wide open? Also, these carbs require a THOROUGH clean, Ultasonic etc.
Most mystery running issues lie in carbs on the Max is why I'd go all in on a carb clean/rebuild.

Plug wire arcing to ground when the plug is installed? Maybe look at it in the dark?

Well, try switching the missing cyl's coil with the other coil adjacent to it, and see if the miss 'follows' the cyl switch.

Cyl #1: LR
Cyl #2: LF
Cyl #3: RR
Cyl#4: RF

Sitting on the bike.

Think of drawing the letter N, starting at the Cyl #1 position.
