[QUOTE="Sinkingfast, post: 474386, member: 15306"] I believe the intake port is from the carb to the reed valves or piston if piston port. Then crankcase to the transfer port (cross flow) or loop ports and in to the cylinder. Most 2cy single carb outboards have asymmetrical respiratory systems..each jug will not tune exactly the same..even with perfect seals and all. Take a warm running outboard engine at low speed and start turning down the low speed needle. One jug will start misfiring before the other jug. It could be just the case here...might just need a turn of the needle... I get crap in the water with my 4 stroke 2.5hp motor in a barrel so pay no attention to the nasty water. [/QUOTE]
