I have 2000 Mercury 40hp Mercury, 4-stroke with pull cord motor. Very basic. I am having weak spark. I have changed CDI units and the problem still existed. Trouble is the ohms numbers are in spec on the stator. I checked the 3 coils and they tested in spec as well. I ohms checked the pulsor coil and it read good. What am I missing? I'm about to spend $$ on a stator as that's the only thing left but the numbers were fine. I checked the ground wire connection on the block and it is solid, but wanted to consult experts.
