johnson 150 has spark only on 4 cylinders

[intimidator3]

i have a 1990 johnson gt 150. boat has sat for 1 month and went to start it and it wouldn't so i checked for fuel and had it checked for spark and only had it on 4 cylinders. 3 on the port side and 1 on the starboard. i checked the coils on those cylinders and they are fine any suggestion would be greatly appreciated. thanks

int3,<br /> I would check for a hung-up(closed) carb float first.If not that,check/test powerpack and stator.
