Hi,


Please describe further your observation:
"....the #3 and #4 ppl plugs are very dark #1 and #2 are better, but not perfect"

Very dark as almost black? Carbon deposits on plug could conduct electricity and drain away spark energy. Could be the answer why engine runs better when you pull #3 cable off ie. more energy reserved for next spark

Try cleaning the plugs a bit. Use wire brush and carb spray. Or put in a new set maybe?
