My Merc 60 (1991) is only running on 2 cylinders (2&3), although there is a good spark on number 1 cylinder. I have changed plugs, HT leads, coil, stator, switch box, fuel pump, fuel filter, fuel lines, fuel tanks, cleaned carbs...3 times, and checked wiring harness! ...If anyone has any suggestions on solving this problem please help!! Thanks in advance.
