The spark in that video is awfully healthy.  I'm having a hard time
envisioning that with a spark that healthy that the plug is NOT firing at
all and is wet.
I would spray around the intake with carb spray to eliminate an intake leak
and then I think I'd pull the valve cover and use a dial indicator to
measure cam lift on both intake and exhaust.
Tis truly a baffling issue.
If all else fails, you might try beating on the distributor with a rubber
chicken, dancing around the car counter clockwise chanting "Oh dark lord
Lucas protect you lowly minion as I toil away on this car.
Hey at this point it can't hurt.
