I'm using tohatsu/nissan 4 hp, heavy beast but in Berkeley chop barely enough i think. Whatever you choose , my experience : provide quality premium gas with stabilizer that is a key for reliable start . Tohatsu/Nissan carburetor goes crazy with any dirt prevalent in cheap gas stations.Also running an engine till you use all fuel after closing a fuel line has not been helpful at all in a 4 stroke engine in my opinion.
