1996 40 hp 2 stroke starts easy but a slight rough idle. Motor gets more rough when put in gear but finally smooths out as power and speed is increased. Good compression (130 lbs both cylinders). Carbs have been rebuilt a year ago. Use Sport Fuel only with 50/1 oil mixture. Lower unit recently rebuilt. Any ideas?
