yes, running cold plugs can cause them to foul.bgulsvig wrote: I repaired the small slit in the boot but it made no difference. I did notice that I am using NGK B8ES spark plugs when my service manual says to run B6ES plugs. Could that be the cause of the black plugs and rough running?...

Not to throw a monkey wrench in, but since you say it is idling fine, the problem may not be pilot related. Pilot circuit effects from idle up to about 1/4 throttle. But your problem is acceleration right?
Have you checked and adjusted the timing with a strobe light? Check it both at idle and under throttle. The procedure is outlined in the shop manual if you have one.
Permanent and perpetual noob.

4) Set fuel levels in bowls with clear tube
5) sync carbs
If you haven't done those two you're just spinning your wheels.
