I've got a 1990 Evinrude 120 V4 and it seems to be chugging some between 1200 and 1500 RPM's Idle sometimes chugs but for the most part it's idling well. About 1000 RPMs in neutral and 800-900 in gear. I've read that it could be a reed not sealing but could it be a jet? I know with these carbs you can pull out the main jet behind the bowl drain plug. But don't they have two more jets? If anyone can help me out that would be awesome!!
