I have a 1999 Johnson J40PLEEA engine. I have had the fuel system and carbs cleaned. Compression on both cylinders is 140 lbs. I've replaced the coil and CDI box and new plugs, but still can't get the engine to rev over 2500 rpm. Had mechanic out to look at it and he said it seems to be something electrical, but he doesn't know what it is. Does anyone have any idea what could be causing this problem. Any help would be greatly appreciated.
